+semver for golang [![Build Status](https://travis-ci.org/blang/semver.svg?branch=master)](https://travis-ci.org/blang/semver) [![GoDoc](https://godoc.org/github.com/blang/semver?status.png)](https://godoc.org/github.com/blang/semver) [![Coverage Status](https://img.shields.io/coveralls/blang/semver.svg)](https://coveralls.io/r/blang/semver?branch=master)
+======
+
+semver is a [Semantic Versioning](http://semver.org/) library written in golang. It fully covers spec version `2.0.0`.
+
+Usage
+-----
+```bash
+$ go get github.com/blang/semver
+```
+Note: Always vendor your dependencies or fix on a specific version tag.
+
+```go
+import github.com/blang/semver
+v1, err := semver.Make("1.0.0-beta")
+v2, err := semver.Make("2.0.0-beta")
+v1.Compare(v2)
+```
+
+Also check the [GoDocs](http://godoc.org/github.com/blang/semver).
+
+Why should I use this lib?
+-----
+
+- Fully spec compatible
+- No reflection
+- No regex
+- Fully tested (Coverage >99%)
+- Readable parsing/validation errors
+- Fast (See [Benchmarks](#benchmarks))
+- Only Stdlib
+- Uses values instead of pointers
+- Many features, see below
+
+
+Features
+-----
+
+- Parsing and validation at all levels
+- Comparator-like comparisons
+- Compare Helper Methods
+- InPlace manipulation
+- Ranges `>=1.0.0 <2.0.0 || >=3.0.0 !3.0.1-beta.1`
+- Wildcards `>=1.x`, `<=2.5.x`
+- Sortable (implements sort.Interface)
+- database/sql compatible (sql.Scanner/Valuer)
+- encoding/json compatible (json.Marshaler/Unmarshaler)
+
+Ranges
+------
+
+A `Range` is a set of conditions which specify which versions satisfy the range.
+
+A condition is composed of an operator and a version. The supported operators are:
+
+- `<1.0.0` Less than `1.0.0`
+- `<=1.0.0` Less than or equal to `1.0.0`
+- `>1.0.0` Greater than `1.0.0`
+- `>=1.0.0` Greater than or equal to `1.0.0`
+- `1.0.0`, `=1.0.0`, `==1.0.0` Equal to `1.0.0`
+- `!1.0.0`, `!=1.0.0` Not equal to `1.0.0`. Excludes version `1.0.0`.
+
+Note that spaces between the operator and the version will be gracefully tolerated.
+
+A `Range` can link multiple `Ranges` separated by space:
+
+Ranges can be linked by logical AND:
+
+  - `>1.0.0 <2.0.0` would match between both ranges, so `1.1.1` and `1.8.7` but not `1.0.0` or `2.0.0`
+  - `>1.0.0 <3.0.0 !2.0.3-beta.2` would match every version between `1.0.0` and `3.0.0` except `2.0.3-beta.2`
+
+Ranges can also be linked by logical OR:
+
+  - `<2.0.0 || >=3.0.0` would match `1.x.x` and `3.x.x` but not `2.x.x`
+
+AND has a higher precedence than OR. It's not possible to use brackets.
+
+Ranges can be combined by both AND and OR
+
+  - `>1.0.0 <2.0.0 || >3.0.0 !4.2.1` would match `1.2.3`, `1.9.9`, `3.1.1`, but not `4.2.1`, `2.1.1`
+
+Range usage:
+
+```
+v, err := semver.Parse("1.2.3")
+range, err := semver.ParseRange(">1.0.0 <2.0.0 || >=3.0.0")
+if range(v) {
+    //valid
+}
+
+```
+
+Example
+-----
+
+Have a look at full examples in [examples/main.go](examples/main.go)
+
+```go
+import github.com/blang/semver
+
+v, err := semver.Make("0.0.1-alpha.preview+123.github")
+fmt.Printf("Major: %d\n", v.Major)
+fmt.Printf("Minor: %d\n", v.Minor)
+fmt.Printf("Patch: %d\n", v.Patch)
+fmt.Printf("Pre: %s\n", v.Pre)
+fmt.Printf("Build: %s\n", v.Build)
+
+// Prerelease versions array
+if len(v.Pre) > 0 {
+    fmt.Println("Prerelease versions:")
+    for i, pre := range v.Pre {
+        fmt.Printf("%d: %q\n", i, pre)
+    }
+}
+
+// Build meta data array
+if len(v.Build) > 0 {
+    fmt.Println("Build meta data:")
+    for i, build := range v.Build {
+        fmt.Printf("%d: %q\n", i, build)
+    }
+}
+
+v001, err := semver.Make("0.0.1")
+// Compare using helpers: v.GT(v2), v.LT, v.GTE, v.LTE
+v001.GT(v) == true
+v.LT(v001) == true
+v.GTE(v) == true
+v.LTE(v) == true
+
+// Or use v.Compare(v2) for comparisons (-1, 0, 1):
+v001.Compare(v) == 1
+v.Compare(v001) == -1
+v.Compare(v) == 0
+
+// Manipulate Version in place:
+v.Pre[0], err = semver.NewPRVersion("beta")
+if err != nil {
+    fmt.Printf("Error parsing pre release version: %q", err)
+}
+
+fmt.Println("\nValidate versions:")
+v.Build[0] = "?"
+
+err = v.Validate()
+if err != nil {
+    fmt.Printf("Validation failed: %s\n", err)
+}
+```

+
+
+Motivation
+-----
+
+I simply couldn't find any lib supporting the full spec. Others were just wrong or used reflection and regex which i don't like.

+# GoJay
+
+<img src="https://github.com/francoispqt/gojay/raw/master/gojay.png" width="200px">
+
+GoJay is a performant JSON encoder/decoder for Golang (currently the most performant, [see benchmarks](#benchmark-results)).
+
+It has a simple API and doesn't use reflection. It relies on small interfaces to decode/encode structures and slices.
+
+Gojay also comes with powerful stream decoding features and an even faster [Unsafe](#unsafe-api) API.
+
+There is also a [code generation tool](https://github.com/francoispqt/gojay/tree/master/gojay) to make usage easier and faster.
+
+# Why another JSON parser?
+
+I looked at other fast decoder/encoder and realised it was mostly hardly readable static code generation or a lot of reflection, poor streaming features, and not so fast in the end.
+
+Also, I wanted to build a decoder that could consume an io.Reader of line or comma delimited JSON, in a JIT way. To consume a flow of JSON objects from a TCP connection for example or from a standard output. Same way I wanted to build an encoder that could encode a flow of data to a io.Writer.
+
+This is how GoJay aims to be a very fast, JIT stream parser with 0 reflection, low allocation with a friendly API.
+
+# Get started
+
+```bash
+go get github.com/francoispqt/gojay
+```
+
+* [Encoder](#encoding)
+* [Decoder](#decoding)
+* [Stream API](#stream-api)
+* [Code Generation](https://github.com/francoispqt/gojay/tree/master/gojay)
+
+## Decoding
+
+Decoding is done through two different API similar to standard `encoding/json`:
+* [Unmarshal](#unmarshal-api)
+* [Decode](#decode-api)
+
+
+Example of basic stucture decoding with Unmarshal:
+```go
+import "github.com/francoispqt/gojay"
+
+type user struct {
+    id int
+    name string
+    email string
+}
+// implement gojay.UnmarshalerJSONObject
+func (u *user) UnmarshalJSONObject(dec *gojay.Decoder, key string) error {
+    switch key {
+    case "id":
+        return dec.Int(&u.id)
+    case "name":
+        return dec.String(&u.name)
+    case "email":
+        return dec.String(&u.email)
+    }
+    return nil
+}
+func (u *user) NKeys() int {
+    return 3
+}
+
+func main() {
+    u := &user{}
+    d := []byte(`{"id":1,"name":"gojay","email":"gojay@email.com"}`)
+    err := gojay.UnmarshalJSONObject(d, u)
+    if err != nil {
+        log.Fatal(err)
+    }
+}
+```
+
+with Decode:
+```go
+func main() {
+    u := &user{}
+    dec := gojay.NewDecoder(bytes.NewReader([]byte(`{"id":1,"name":"gojay","email":"gojay@email.com"}`)))
+    err := dec.DecodeObject(d, u)
+    if err != nil {
+        log.Fatal(err)
+    }
+}
+```
+
+### Unmarshal API
+
+Unmarshal API decodes a `[]byte` to a given pointer with a single function.
+
+Behind the doors, Unmarshal API borrows a `*gojay.Decoder` resets its settings and decodes the data to the given pointer and releases the `*gojay.Decoder` to the pool when it finishes, whether it encounters an error or not.
+
+If it cannot find the right Decoding strategy for the type of the given pointer, it returns an `InvalidUnmarshalError`. You can test the error returned by doing `if ok := err.(InvalidUnmarshalError); ok {}`.
+
+Unmarshal API comes with three functions:
+* Unmarshal
+```go
+func Unmarshal(data []byte, v interface{}) error
+```
+
+* UnmarshalJSONObject
+```go
+func UnmarshalJSONObject(data []byte, v gojay.UnmarshalerJSONObject) error
+```
+
+* UnmarshalJSONArray
+```go
+func UnmarshalJSONArray(data []byte, v gojay.UnmarshalerJSONArray) error
+```
+
+
+### Decode API
+
+Decode API decodes a `[]byte` to a given pointer by creating or borrowing a `*gojay.Decoder` with an `io.Reader` and calling `Decode` methods.
+
+__Getting a *gojay.Decoder or Borrowing__
+
+You can either get a fresh `*gojay.Decoder` calling `dec := gojay.NewDecoder(io.Reader)` or borrow one from the pool by calling `dec := gojay.BorrowDecoder(io.Reader)`.
+
+After using a decoder, you can release it by calling `dec.Release()`. Beware, if you reuse the decoder after releasing it, it will panic with an error of type `InvalidUsagePooledDecoderError`. If you want to fully benefit from the pooling, you must release your decoders after using.
+
+Example getting a fresh an releasing:
+```go
+str := ""
+dec := gojay.NewDecoder(strings.NewReader(`"test"`))
+defer dec.Release()
+if err := dec.Decode(&str); err != nil {
+    log.Fatal(err)
+}
+```
+Example borrowing a decoder and releasing:
+```go
+str := ""
+dec := gojay.BorrowDecoder(strings.NewReader(`"test"`))
+defer dec.Release()
+if err := dec.Decode(&str); err != nil {
+    log.Fatal(err)
+}
+```
+
+`*gojay.Decoder` has multiple methods to decode to specific types:
+* Decode
+```go
+func (dec *gojay.Decoder) Decode(v interface{}) error
+```
+* DecodeObject
+```go
+func (dec *gojay.Decoder) DecodeObject(v gojay.UnmarshalerJSONObject) error
+```
+* DecodeArray
+```go
+func (dec *gojay.Decoder) DecodeArray(v gojay.UnmarshalerJSONArray) error
+```
+* DecodeInt
+```go
+func (dec *gojay.Decoder) DecodeInt(v *int) error
+```
+* DecodeBool
+```go
+func (dec *gojay.Decoder) DecodeBool(v *bool) error
+```
+* DecodeString
+```go
+func (dec *gojay.Decoder) DecodeString(v *string) error
+```
+
+All DecodeXxx methods are used to decode top level JSON values. If you are decoding keys or items of a JSON object or array, don't use the Decode methods.
+
+Example:
+```go
+reader := strings.NewReader(`"John Doe"`)
+dec := NewDecoder(reader)
+
+var str string
+err := dec.DecodeString(&str)
+if err != nil {
+    log.Fatal(err)
+}
+
+fmt.Println(str) // John Doe
+```
+
+### Structs and Maps
+#### UnmarshalerJSONObject Interface
+
+To unmarshal a JSON object to a structure, the structure must implement the `UnmarshalerJSONObject` interface:
+```go
+type UnmarshalerJSONObject interface {
+	UnmarshalJSONObject(*gojay.Decoder, string) error
+	NKeys() int
+}
+```
+`UnmarshalJSONObject` method takes two arguments, the first one is a pointer to the Decoder (*gojay.Decoder) and the second one is the string value of the current key being parsed. If the JSON data is not an object, the UnmarshalJSONObject method will never be called.
+
+`NKeys` method must return the number of keys to Unmarshal in the JSON object or 0. If zero is returned, all keys will be parsed.
+
+Example of implementation for a struct:
+```go
+type user struct {
+    id int
+    name string
+    email string
+}
+// implement UnmarshalerJSONObject
+func (u *user) UnmarshalJSONObject(dec *gojay.Decoder, key string) error {
+    switch key {
+    case "id":
+        return dec.Int(&u.id)
+    case "name":
+        return dec.String(&u.name)
+    case "email":
+        return dec.String(&u.email)
+    }
+    return nil
+}
+func (u *user) NKeys() int {
+    return 3
+}
+```
+
+Example of implementation for a `map[string]string`:
+```go
+// define our custom map type implementing UnmarshalerJSONObject
+type message map[string]string
+
+// Implementing Unmarshaler
+func (m message) UnmarshalJSONObject(dec *gojay.Decoder, k string) error {
+	str := ""
+	err := dec.String(&str)
+	if err != nil {
+		return err
+	}
+	m[k] = str
+	return nil
+}
+
+// we return 0, it tells the Decoder to decode all keys
+func (m message) NKeys() int {
+	return 0
+}
+```
+
+### Arrays, Slices and Channels
+
+To unmarshal a JSON object to a slice an array or a channel, it must implement the UnmarshalerJSONArray interface:
+```go
+type UnmarshalerJSONArray interface {
+	UnmarshalJSONArray(*gojay.Decoder) error
+}
+```
+UnmarshalJSONArray method takes one argument, a pointer to the Decoder (*gojay.Decoder). If the JSON data is not an array, the Unmarshal method will never be called.
+
+Example of implementation with a slice:
+```go
+type testSlice []string
+// implement UnmarshalerJSONArray
+func (t *testSlice) UnmarshalJSONArray(dec *gojay.Decoder) error {
+	str := ""
+	if err := dec.String(&str); err != nil {
+		return err
+	}
+	*t = append(*t, str)
+	return nil
+}
+
+func main() {
+	dec := gojay.BorrowDecoder(strings.NewReader(`["Tom", "Jim"]`))
+	var slice testSlice
+	err := dec.DecodeArray(&slice)
+	if err != nil {
+		log.Fatal(err)
+	}
+	fmt.Println(slice) // [Tom Jim]
+	dec.Release()
+}
+```
+
+Example of implementation with a channel:
+```go
+type testChannel chan string
+// implement UnmarshalerJSONArray
+func (c testChannel) UnmarshalJSONArray(dec *gojay.Decoder) error {
+	str := ""
+	if err := dec.String(&str); err != nil {
+		return err
+	}
+	c <- str
+	return nil
+}
+
+func main() {
+	dec := gojay.BorrowDecoder(strings.NewReader(`["Tom", "Jim"]`))
+	c := make(testChannel, 2)
+	err := dec.DecodeArray(c)
+	if err != nil {
+		log.Fatal(err)
+	}
+	for i := 0; i < 2; i++ {
+		fmt.Println(<-c)
+	}
+	close(c)
+	dec.Release()
+}
+```
+
+Example of implementation with an array:
+```go
+type testArray [3]string
+// implement UnmarshalerJSONArray
+func (a *testArray) UnmarshalJSONArray(dec *Decoder) error {
+	var str string
+	if err := dec.String(&str); err != nil {
+		return err
+	}
+	a[dec.Index()] = str
+	return nil
+}
+
+func main() {
+	dec := gojay.BorrowDecoder(strings.NewReader(`["Tom", "Jim", "Bob"]`))
+	var a testArray
+	err := dec.DecodeArray(&a)
+	fmt.Println(a) // [Tom Jim Bob]
+	dec.Release()
+}
+```
+
+### Other types
+To decode other types (string, int, int32, int64, uint32, uint64, float, booleans), you don't need to implement any interface.
+
+Example of encoding strings:
+```go
+func main() {
+    json := []byte(`"Jay"`)
+    var v string
+    err := gojay.Unmarshal(json, &v)
+    if err != nil {
+        log.Fatal(err)
+    }
+    fmt.Println(v) // Jay
+}
+```
+
+### Decode values methods
+When decoding a JSON object of a JSON array using `UnmarshalerJSONObject` or `UnmarshalerJSONArray` interface, the `gojay.Decoder` provides dozens of methods to Decode multiple types.
+
+Non exhaustive list of methods available (to see all methods, check the godoc):
+```go
+dec.Int
+dec.Int8
+dec.Int16
+dec.Int32
+dec.Int64
+dec.Uint8
+dec.Uint16
+dec.Uint32
+dec.Uint64
+dec.String
+dec.Time
+dec.Bool
+dec.SQLNullString
+dec.SQLNullInt64
+```
+
+
+## Encoding
+
+Encoding is done through two different API similar to standard `encoding/json`:
+* [Marshal](#marshal-api)
+* [Encode](#encode-api)
+
+Example of basic structure encoding with Marshal:
+```go
+import "github.com/francoispqt/gojay"
+
+type user struct {
+	id    int
+	name  string
+	email string
+}
+
+// implement MarshalerJSONObject
+func (u *user) MarshalJSONObject(enc *gojay.Encoder) {
+	enc.IntKey("id", u.id)
+	enc.StringKey("name", u.name)
+	enc.StringKey("email", u.email)
+}
+func (u *user) IsNil() bool {
+	return u == nil
+}
+
+func main() {
+	u := &user{1, "gojay", "gojay@email.com"}
+	b, err := gojay.MarshalJSONObject(u)
+	if err != nil {
+		log.Fatal(err)
+	}
+	fmt.Println(string(b)) // {"id":1,"name":"gojay","email":"gojay@email.com"}
+}
+```
+
+with Encode:
+```go
+func main() {
+	u := &user{1, "gojay", "gojay@email.com"}
+	b := strings.Builder{}
+	enc := gojay.NewEncoder(&b)
+	if err := enc.Encode(u); err != nil {
+		log.Fatal(err)
+	}
+	fmt.Println(b.String()) // {"id":1,"name":"gojay","email":"gojay@email.com"}
+}
+```
+
+### Marshal API
+
+Marshal API encodes a value to a JSON `[]byte` with a single function.
+
+Behind the doors, Marshal API borrows a `*gojay.Encoder` resets its settings and encodes the data to an internal byte buffer and releases the `*gojay.Encoder` to the pool when it finishes, whether it encounters an error or not.
+
+If it cannot find the right Encoding strategy for the type of the given value, it returns an `InvalidMarshalError`. You can test the error returned by doing `if ok := err.(InvalidMarshalError); ok {}`.
+
+Marshal API comes with three functions:
+* Marshal
+```go
+func Marshal(v interface{}) ([]byte, error)
+```
+
+* MarshalJSONObject
+```go
+func MarshalJSONObject(v gojay.MarshalerJSONObject) ([]byte, error)
+```
+
+* MarshalJSONArray
+```go
+func MarshalJSONArray(v gojay.MarshalerJSONArray) ([]byte, error)
+```
+
+### Encode API
+
+Encode API decodes a value to JSON by creating or borrowing a `*gojay.Encoder` sending it to an `io.Writer` and calling `Encode` methods.
+
+__Getting a *gojay.Encoder or Borrowing__
+
+You can either get a fresh `*gojay.Encoder` calling `enc := gojay.NewEncoder(io.Writer)` or borrow one from the pool by calling `enc := gojay.BorrowEncoder(io.Writer)`.
+
+After using an encoder, you can release it by calling `enc.Release()`. Beware, if you reuse the encoder after releasing it, it will panic with an error of type `InvalidUsagePooledEncoderError`. If you want to fully benefit from the pooling, you must release your encoders after using.
+
+Example getting a fresh encoder an releasing:
+```go
+str := "test"
+b := strings.Builder{}
+enc := gojay.NewEncoder(&b)
+defer enc.Release()
+if err := enc.Encode(str); err != nil {
+    log.Fatal(err)
+}
+```
+Example borrowing an encoder and releasing:
+```go
+str := "test"
+b := strings.Builder{}
+enc := gojay.BorrowEncoder(b)
+defer enc.Release()
+if err := enc.Encode(str); err != nil {
+    log.Fatal(err)
+}
+```
+
+`*gojay.Encoder` has multiple methods to encoder specific types to JSON:
+* Encode
+```go
+func (enc *gojay.Encoder) Encode(v interface{}) error
+```
+* EncodeObject
+```go
+func (enc *gojay.Encoder) EncodeObject(v gojay.MarshalerJSONObject) error
+```
+* EncodeArray
+```go
+func (enc *gojay.Encoder) EncodeArray(v gojay.MarshalerJSONArray) error
+```
+* EncodeInt
+```go
+func (enc *gojay.Encoder) EncodeInt(n int) error
+```
+* EncodeInt64
+```go
+func (enc *gojay.Encoder) EncodeInt64(n int64) error
+```
+* EncodeFloat
+```go
+func (enc *gojay.Encoder) EncodeFloat(n float64) error
+```
+* EncodeBool
+```go
+func (enc *gojay.Encoder) EncodeBool(v bool) error
+```
+* EncodeString
+```go
+func (enc *gojay.Encoder) EncodeString(s string) error
+```
+
+### Structs and Maps
+
+To encode a structure, the structure must implement the MarshalerJSONObject interface:
+```go
+type MarshalerJSONObject interface {
+	MarshalJSONObject(enc *gojay.Encoder)
+	IsNil() bool
+}
+```
+`MarshalJSONObject` method takes one argument, a pointer to the Encoder (*gojay.Encoder). The method must add all the keys in the JSON Object by calling Decoder's methods.
+
+IsNil method returns a boolean indicating if the interface underlying value is nil or not. It is used to safely ensure that the underlying value is not nil without using Reflection.
+
+Example of implementation for a struct:
+```go
+type user struct {
+	id    int
+	name  string
+	email string
+}
+
+// implement MarshalerJSONObject
+func (u *user) MarshalJSONObject(enc *gojay.Encoder) {
+	enc.IntKey("id", u.id)
+	enc.StringKey("name", u.name)
+	enc.StringKey("email", u.email)
+}
+func (u *user) IsNil() bool {
+	return u == nil
+}
+```
+
+Example of implementation for a `map[string]string`:
+```go
+// define our custom map type implementing MarshalerJSONObject
+type message map[string]string
+
+// Implementing Marshaler
+func (m message) MarshalJSONObject(enc *gojay.Encoder) {
+	for k, v := range m {
+		enc.StringKey(k, v)
+	}
+}
+
+func (m message) IsNil() bool {
+	return m == nil
+}
+```
+
+### Arrays and Slices
+To encode an array or a slice, the slice/array must implement the MarshalerJSONArray interface:
+```go
+type MarshalerJSONArray interface {
+	MarshalJSONArray(enc *gojay.Encoder)
+	IsNil() bool
+}
+```
+`MarshalJSONArray` method takes one argument, a pointer to the Encoder (*gojay.Encoder). The method must add all element in the JSON Array by calling Decoder's methods.
+
+`IsNil` method returns a boolean indicating if the interface underlying value is nil(empty) or not. It is used to safely ensure that the underlying value is not nil without using Reflection and also to in `OmitEmpty` feature.
+
+Example of implementation:
+```go
+type users []*user
+// implement MarshalerJSONArray
+func (u *users) MarshalJSONArray(enc *gojay.Encoder) {
+	for _, e := range u {
+		enc.Object(e)
+	}
+}
+func (u *users) IsNil() bool {
+	return len(u) == 0
+}
+```
+
+### Other types
+To encode other types (string, int, float, booleans), you don't need to implement any interface.
+
+Example of encoding strings:
+```go
+func main() {
+	name := "Jay"
+	b, err := gojay.Marshal(name)
+	if err != nil {
+		log.Fatal(err)
+	}
+	fmt.Println(string(b)) // "Jay"
+}
+```
+
+# Stream API
+
+### Stream Decoding
+GoJay ships with a powerful stream decoder.
+
+It allows to read continuously from an io.Reader stream and do JIT decoding writing unmarshalled JSON to a channel to allow async consuming.
+
+When using the Stream API, the Decoder implements context.Context to provide graceful cancellation.
+
+To decode a stream of JSON, you must call `gojay.Stream.DecodeStream` and pass it a `UnmarshalerStream` implementation.
+
+```go
+type UnmarshalerStream interface {
+	UnmarshalStream(*StreamDecoder) error
+}
+```
+
+Example of implementation of stream reading from a WebSocket connection:
+```go
+// implement UnmarshalerStream
+type ChannelStream chan *user
+
+func (c ChannelStream) UnmarshalStream(dec *gojay.StreamDecoder) error {
+	u := &user{}
+	if err := dec.Object(u); err != nil {
+		return err
+	}
+	c <- u
+	return nil
+}
+
+func main() {
+	// get our websocket connection
+	origin := "http://localhost/"
+	url := "ws://localhost:12345/ws"
+	ws, err := websocket.Dial(url, "", origin)
+	if err != nil {
+		log.Fatal(err)
+	}
+	// create our channel which will receive our objects
+	streamChan := ChannelStream(make(chan *user))
+	// borrow a decoder
+	dec := gojay.Stream.BorrowDecoder(ws)
+	// start decoding, it will block until a JSON message is decoded from the WebSocket
+	// or until Done channel is closed

+
+### Stream Encoding
+GoJay ships with a powerful stream encoder part of the Stream API.
+
+It allows to write continuously to an io.Writer and do JIT encoding of data fed to a channel to allow async consuming. You can set multiple consumers on the channel to be as performant as possible. Consumers are non blocking and are scheduled individually in their own go routine.
+
+When using the Stream API, the Encoder implements context.Context to provide graceful cancellation.
+
+To encode a stream of data, you must call `EncodeStream` and pass it a `MarshalerStream` implementation.
+
+```go
+type MarshalerStream interface {
+	MarshalStream(enc *gojay.StreamEncoder)
+}
+```
+
+Example of implementation of stream writing to a WebSocket:
+```go
+// Our structure which will be pushed to our stream
+type user struct {
+	id    int
+	name  string
+	email string
+}
+
+func (u *user) MarshalJSONObject(enc *gojay.Encoder) {
+	enc.IntKey("id", u.id)
+	enc.StringKey("name", u.name)
+	enc.StringKey("email", u.email)
+}
+func (u *user) IsNil() bool {
+	return u == nil
+}
+
+// Our MarshalerStream implementation
+type StreamChan chan *user
+
+func (s StreamChan) MarshalStream(enc *gojay.StreamEncoder) {
+	select {
+	case <-enc.Done():
+		return
+	case o := <-s:
+		enc.Object(o)
+	}
+}
+
+// Our main function
+func main() {
+	// get our websocket connection
+	origin := "http://localhost/"
+	url := "ws://localhost:12345/ws"
+	ws, err := websocket.Dial(url, "", origin)
+	if err != nil {
+		log.Fatal(err)
+	}
+	// we borrow an encoder set stdout as the writer,
+	// set the number of consumer to 10
+	// and tell the encoder to separate each encoded element
+	// added to the channel by a new line character
+	enc := gojay.Stream.BorrowEncoder(ws).NConsumer(10).LineDelimited()
+	// instantiate our MarshalerStream
+	s := StreamChan(make(chan *user))
+	// start the stream encoder
+	// will block its goroutine until enc.Cancel(error) is called
+	// or until something is written to the channel
+	go enc.EncodeStream(s)
+	// write to our MarshalerStream
+	for i := 0; i < 1000; i++ {
+		s <- &user{i, "username", "user@email.com"}
+	}
+	// Wait
+	<-enc.Done()
+}
+```
+
+# Unsafe API
+
+Unsafe API has the same functions than the regular API, it only has `Unmarshal API` for now. It is unsafe because it makes assumptions on the quality of the given JSON.
+
+If you are not sure if your JSON is valid, don't use the Unsafe API.
+
+Also, the `Unsafe` API does not copy the buffer when using Unmarshal API, which, in case of string decoding, can lead to data corruption if a byte buffer is reused. Using the `Decode` API makes `Unsafe` API safer as the io.Reader relies on `copy` builtin method and `Decoder` will have its own internal buffer :)
+
+Access the `Unsafe` API this way:
+```go
+gojay.Unsafe.Unmarshal(b, v)
+```
+
+
+# Benchmarks
+
+Benchmarks encode and decode three different data based on size (small, medium, large).
+
+To run benchmark for decoder:
+```bash
+cd $GOPATH/src/github.com/francoispqt/gojay/benchmarks/decoder && make bench
+```
+
+To run benchmark for encoder:
+```bash
+cd $GOPATH/src/github.com/francoispqt/gojay/benchmarks/encoder && make bench
+```

+// On top of the simple interfaces to implement, gojay provides lots of helpers to decode and encode

-Equal returns true iff protocol buffers a and b are equal.
-The arguments must both be pointers to protocol buffer structs.

-Equality is defined in this way:
-  - Two messages are equal iff they are the same type,
-    corresponding fields are equal, unknown field sets
-    are equal, and extensions sets are equal.
-  - Two set scalar fields are equal iff their values are equal.
-    If the fields are of a floating-point type, remember that
-    NaN != x for all x, including NaN. If the message is defined
-    in a proto3 .proto file, fields are not "set"; specifically,
-    zero length proto3 "bytes" fields are equal (nil == {}).
-  - Two repeated fields are equal iff their lengths are the same,
-    and their corresponding elements are equal. Note a "bytes" field,
-    although represented by []byte, is not a repeated field and the
-    rule for the scalar fields described above applies.
-  - Two unset fields are equal.
-  - Two unknown field sets are equal if their current
-    encoded state is equal.
-  - Two extension sets are equal iff they have corresponding
-    elements that are pairwise equal.
-  - Two map fields are equal iff their lengths are the same,
-    and they contain the same set of elements. Zero-length map
-    fields are equal.
-  - Every other combination of things are not equal.

-Package proto converts data structures to and from the wire format of
-protocol buffers.  It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed by the enclosing message's name, or by the
-	enum's type name if it is a top-level enum. Enum types have a String
-	method, and a Enum method to assist in message construction.
-  - Nested messages, groups and enums have type names prefixed with the name of
-	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
-	package example;
-
-	enum FOO { X = 17; }
-
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	  oneof union {
-	    int32 number = 6;
-	    string name = 7;

-	// corresponds to a particular definition.  This information is intended
-	// to be useful to IDEs, code indexers, documentation generators, and similar
-	// tools.
-	//
-	// For example, say we have a file like:
-	//   message Foo {
-	//     optional string foo = 1;
-	//   }
-	// Let's look at just the field definition:
-	//   optional string foo = 1;
-	//   ^       ^^     ^^  ^  ^^^
-	//   a       bc     de  f  ghi
-	// We have the following locations:
-	//   span   path               represents
-	//   [a,i)  [ 4, 0, 2, 0 ]     The whole field definition.
-	//   [a,b)  [ 4, 0, 2, 0, 4 ]  The label (optional).
-	//   [c,d)  [ 4, 0, 2, 0, 5 ]  The type (string).
-	//   [e,f)  [ 4, 0, 2, 0, 1 ]  The name (foo).
-	//   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
-	//
-	// Notes:
-	// - A location may refer to a repeated field itself (i.e. not to any
-	//   particular index within it).  This is used whenever a set of elements are
-	//   logically enclosed in a single code segment.  For example, an entire
-	//   extend block (possibly containing multiple extension definitions) will
-	//   have an outer location whose path refers to the "extensions" repeated
-	//   field without an index.
-	// - Multiple locations may have the same path.  This happens when a single
-	//   logical declaration is spread out across multiple places.  The most
-	//   obvious example is the "extend" block again -- there may be multiple
-	//   extend blocks in the same scope, each of which will have the same path.
-	// - A location's span is not always a subset of its parent's span.  For
-	//   example, the "extendee" of an extension declaration appears at the
-	//   beginning of the "extend" block and is shared by all extensions within
-	//   the block.
-	// - Just because a location's span is a subset of some other location's span
-	//   does not mean that it is a descendent.  For example, a "group" defines
-	//   both a type and a field in a single declaration.  Thus, the locations
-	//   corresponding to the type and field and their components will overlap.
-	// - Code which tries to interpret locations should probably be designed to
-	//   ignore those that it doesn't understand, as more types of locations could
-	//   be recorded in the future.

-	// Each element is a field number or an index.  They form a path from

-	// refers to:
-	//   file.message_type(3)  // 4, 3
-	//       .field(7)         // 2, 7

-	//   repeated FieldDescriptorProto field = 2;
-	// and FieldDescriptorProto.name has field number 1:

-	//
-	// Thus, the above path gives the location of a field name.  If we removed

-	Span []int32 `protobuf:"varint,2,rep,packed,name=span" json:"span,omitempty"`
-	// If this SourceCodeInfo represents a complete declaration, these are any
-	// comments appearing before and after the declaration which appear to be

-	//
-	// A series of line comments appearing on consecutive lines, with no other
-	// tokens appearing on those lines, will be treated as a single comment.
-	//
-	// leading_detached_comments will keep paragraphs of comments that appear

-	// separated by empty lines, will be one comment element in the repeated
-	// field.

-	// stripped out.  For block comments, leading whitespace and an asterisk
-	// will be stripped from the beginning of each line other than the first.

-// Options
-
-// Each of the definitions above may have "options" attached.  These are
-// just annotations which may cause code to be generated slightly differently
-// or may contain hints for code that manipulates protocol messages.
-//
-// Clients may define custom options as extensions of the *Options messages.
-// These extensions may not yet be known at parsing time, so the parser cannot
-// store the values in them.  Instead it stores them in a field in the *Options
-// message called uninterpreted_option. This field must have the same name
-// across all *Options messages. We then use this field to populate the
-// extensions when we build a descriptor, at which point all protos have been
-// parsed and so all extensions are known.
-//
-// Extension numbers for custom options may be chosen as follows:
-// * For options which will only be used within a single application or
-//   organization, or for experimental options, use field numbers 50000
-//   through 99999.  It is up to you to ensure that you do not use the
-//   same number for multiple options.
-// * For options which will be published and used publicly by multiple
-//   independent entities, e-mail protobuf-global-extension-registry@google.com
-//   to reserve extension numbers. Simply provide your project name (e.g.
-//   Objective-C plugin) and your project website (if available) -- there's no
-//   need to explain how you intend to use them. Usually you only need one
-//   extension number. You can declare multiple options with only one extension
-//   number by putting them in a sub-message. See the Custom Options section of
-//   the docs for examples:
-//   https://developers.google.com/protocol-buffers/docs/proto#options
-//   If this turns out to be popular, a web service will be set up
-//   to automatically assign option numbers.

-  //   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
-  //
-  // Notes:
-  // - A location may refer to a repeated field itself (i.e. not to any
-  //   particular index within it).  This is used whenever a set of elements are
-  //   logically enclosed in a single code segment.  For example, an entire
-  //   extend block (possibly containing multiple extension definitions) will
-  //   have an outer location whose path refers to the "extensions" repeated
-  //   field without an index.
-  // - Multiple locations may have the same path.  This happens when a single
-  //   logical declaration is spread out across multiple places.  The most
-  //   obvious example is the "extend" block again -- there may be multiple
-  //   extend blocks in the same scope, each of which will have the same path.
-  // - A location's span is not always a subset of its parent's span.  For
-  //   example, the "extendee" of an extension declaration appears at the
-  //   beginning of the "extend" block and is shared by all extensions within
-  //   the block.
-  // - Just because a location's span is a subset of some other location's span
-  //   does not mean that it is a descendent.  For example, a "group" defines
-  //   both a type and a field in a single declaration.  Thus, the locations
-  //   corresponding to the type and field and their components will overlap.
-  // - Code which tries to interpret locations should probably be designed to
-  //   ignore those that it doesn't understand, as more types of locations could
-  //   be recorded in the future.

-    //       .field(7)         // 2, 7
-    //       .name()           // 1

+# uuid ![build status](https://travis-ci.org/google/uuid.svg?branch=master)
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services. 
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid).  It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice.  One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).

+# Contribution Guidelines
+
+We welcome contribution and improvements.
+
+## Guiding Principles
+
+To begin with here is a draft from an email exchange:
+
+ * take compatibility seriously (our semvers, compatibility with older go versions, etc)
+ * don't tag untested code for release
+ * beware of baking in implicit behavior based on other libraries/tools choices
+ * be as high-fidelity as possible in plumbing through LDAP data (don't mask errors or reduce power of someone using the library)

+# Basic LDAP v3 functionality for the GO programming language.
+
+## Features:
+
+ - Connecting to LDAP server (non-TLS, TLS, STARTTLS)
+ - Binding to LDAP server
+ - Searching for entries
+ - Filter Compile / Decompile
+ - Paging Search Results
+ - Modify Requests / Responses
+ - Add Requests / Responses
+ - Delete Requests / Responses
+ - Modify DN Requests / Responses
+
+## Examples:
+
+ - search
+ - modify
+
+## Go Modules:
+
+`go get github.com/go-ldap/ldap/v3`
+
+As go-ldap was v2+ when Go Modules came out, updating to Go Modules would be considered a breaking change.
+
+To maintain backwards compatability, we ultimately decided to use subfolders (as v3 was already a branch).
+Whilst this duplicates the code, we can move toward implementing a backwards-compatible versioning system that allows for code reuse.
+The alternative would be to increment the version number, however we believe that this would confuse users as v3 is in line with LDAPv3 (RFC-4511)
+https://tools.ietf.org/html/rfc4511
+
+
+For more info, please visit the pull request that updated to modules.
+https://github.com/go-ldap/ldap/pull/247
+
+To install with `GOMODULE111=off`, use `go get github.com/go-ldap/ldap`
+https://golang.org/cmd/go/#hdr-Legacy_GOPATH_go_get
+
+As always, we are looking for contributors with great ideas on how to best move forward.
+
+
+## Contributing:
+
+Bug reports and pull requests are welcome!

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-// Package mapstructure exposes functionality to convert an arbitrary
-// map[string]interface{} into a native Go structure.
+// Package mapstructure exposes functionality to convert one arbitrary
+// Go type into another, typically to convert a map[string]interface{}
+// into a native Go structure.
 //
 // The Go structure can be arbitrarily complex, containing slices,
 // other structs, etc. and the decoder will properly decode nested
 // maps and so on into the proper structures in the native Go struct.
 // See the examples to see what the decoder is capable of.
+//
+// The simplest function to start with is Decode.
+//
+// Field Tags
+//
+// When decoding to a struct, mapstructure will use the field name by
+// default to perform the mapping. For example, if a struct has a field
+// "Username" then mapstructure will look for a key in the source value
+// of "username" (case insensitive).
+//
+//     type User struct {
+//         Username string
+//     }
+//
+// You can change the behavior of mapstructure by using struct tags.
+// The default struct tag that mapstructure looks for is "mapstructure"
+// but you can customize it using DecoderConfig.
+//
+// Renaming Fields
+//
+// To rename the key that mapstructure looks for, use the "mapstructure"
+// tag and set a value directly. For example, to change the "username" example
+// above to "user":
+//
+//     type User struct {
+//         Username string `mapstructure:"user"`
+//     }
+//
+// Embedded Structs and Squashing
+//
+// Embedded structs are treated as if they're another field with that name.
+// By default, the two structs below are equivalent when decoding with
+// mapstructure:
+//
+//     type Person struct {
+//         Name string
+//     }
+//
+//     type Friend struct {
+//         Person
+//     }
+//
+//     type Friend struct {
+//         Person Person
+//     }
+//
+// This would require an input that looks like below:
+//
+//     map[string]interface{}{
+//         "person": map[string]interface{}{"name": "alice"},
+//     }
+//
+// If your "person" value is NOT nested, then you can append ",squash" to
+// your tag value and mapstructure will treat it as if the embedded struct
+// were part of the struct directly. Example:
+//
+//     type Friend struct {
+//         Person `mapstructure:",squash"`
+//     }
+//
+// Now the following input would be accepted:
+//
+//     map[string]interface{}{
+//         "name": "alice",
+//     }
+//
+// DecoderConfig has a field that changes the behavior of mapstructure
+// to always squash embedded structs.
+//
+// Remainder Values
+//
+// If there are any unmapped keys in the source value, mapstructure by
+// default will silently ignore them. You can error by setting ErrorUnused
+// in DecoderConfig. If you're using Metadata you can also maintain a slice
+// of the unused keys.
+//
+// You can also use the ",remain" suffix on your tag to collect all unused
+// values in a map. The field with this tag MUST be a map type and should
+// probably be a "map[string]interface{}" or "map[interface{}]interface{}".
+// See example below:
+//
+//     type Friend struct {
+//         Name  string
+//         Other map[string]interface{} `mapstructure:",remain"`
+//     }
+//
+// Given the input below, Other would be populated with the other
+// values that weren't used (everything but "name"):
+//
+//     map[string]interface{}{
+//         "name":    "bob",
+//         "address": "123 Maple St.",
+//     }
+//
+// Other Configuration
+//
+// mapstructure is highly configurable. See the DecoderConfig struct
+// for other features and options that are supported.

+## Contributing
+
+Thank you for your interest in go-toml! We appreciate you considering
+contributing to go-toml!
+
+The main goal is the project is to provide an easy-to-use TOML
+implementation for Go that gets the job done and gets out of your way –
+dealing with TOML is probably not the central piece of your project.
+
+As the single maintainer of go-toml, time is scarce. All help, big or
+small, is more than welcomed!
+
+### Ask questions
+
+Any question you may have, somebody else might have it too. Always feel
+free to ask them on the [issues tracker][issues-tracker].  We will try to
+answer them as clearly and quickly as possible, time permitting.
+
+Asking questions also helps us identify areas where the documentation needs
+improvement, or new features that weren't envisioned before. Sometimes, a
+seemingly innocent question leads to the fix of a bug. Don't hesitate and
+ask away!
+
+### Improve the documentation
+
+The best way to share your knowledge and experience with go-toml is to
+improve the documentation. Fix a typo, clarify an interface, add an
+example, anything goes!
+
+The documentation is present in the [README][readme] and thorough the
+source code. On release, it gets updated on [GoDoc][godoc]. To make a
+change to the documentation, create a pull request with your proposed
+changes. For simple changes like that, the easiest way to go is probably
+the "Fork this project and edit the file" button on Github, displayed at
+the top right of the file. Unless it's a trivial change (for example a
+typo), provide a little bit of context in your pull request description or
+commit message.
+
+### Report a bug
+
+Found a bug! Sorry to hear that :(. Help us and other track them down and
+fix by reporting it. [File a new bug report][bug-report] on the [issues
+tracker][issues-tracker]. The template should provide enough guidance on
+what to include. When in doubt: add more details! By reducing ambiguity and
+providing more information, it decreases back and forth and saves everyone
+time.
+
+### Code changes
+
+Want to contribute a patch? Very happy to hear that!
+
+First, some high-level rules:
+
+* A short proposal with some POC code is better than a lengthy piece of
+  text with no code. Code speaks louder than words.
+* No backward-incompatible patch will be accepted unless discussed.
+  Sometimes it's hard, and Go's lack of versioning by default does not
+  help, but we try not to break people's programs unless we absolutely have
+  to.
+* If you are writing a new feature or extending an existing one, make sure
+  to write some documentation.
+* Bug fixes need to be accompanied with regression tests.
+* New code needs to be tested.
+* Your commit messages need to explain why the change is needed, even if
+  already included in the PR description.
+
+It does sound like a lot, but those best practices are here to save time
+overall and continuously improve the quality of the project, which is
+something everyone benefits from.
+
+#### Get started
+
+The fairly standard code contribution process looks like that:
+
+1. [Fork the project][fork].
+2. Make your changes, commit on any branch you like.
+3. [Open up a pull request][pull-request]
+4. Review, potential ask for changes.
+5. Merge. You're in!
+
+Feel free to ask for help! You can create draft pull requests to gather
+some early feedback!
+
+#### Run the tests
+
+You can run tests for go-toml using Go's test tool: `go test ./...`.
+When creating a pull requests, all tests will be ran on Linux on a few Go
+versions (Travis CI), and on Windows using the latest Go version
+(AppVeyor).
+
+#### Style
+
+Try to look around and follow the same format and structure as the rest of
+the code. We enforce using `go fmt` on the whole code base.
+
+---
+
+### Maintainers-only
+
+#### Merge pull request
+
+Checklist:
+
+* Passing CI.
+* Does not introduce backward-incompatible changes (unless discussed).
+* Has relevant doc changes.
+* Has relevant unit tests.
+
+1. Merge using "squash and merge".
+2. Make sure to edit the commit message to keep all the useful information
+   nice and clean.
+3. Make sure the commit title is clear and contains the PR number (#123).
+
+#### New release
+
+1. Go to [releases][releases]. Click on "X commits to master since this
+   release".
+2. Make note of all the changes. Look for backward incompatible changes,
+   new features, and bug fixes.
+3. Pick the new version using the above and semver.
+4. Create a [new release][new-release].
+5. Follow the same format as [1.1.0][release-110].

+## Roadmap
+
+With the upcoming [Go2 error proposals](https://go.googlesource.com/proposal/+/master/design/go2draft.md) this package is moving into maintenance mode. The roadmap for a 1.0 release is as follows:
+
+- 0.9. Remove pre Go 1.9 and Go 1.10 support, address outstanding pull requests (if possible)
+- 1.0. Final release.
+
 ## Contributing
 
-We welcome pull requests, bug fixes and issue reports. With that said, the bar for adding new symbols to this package is intentionally set high.
+Because of the Go2 errors changes, this package is not accepting proposals for new functionality. With that said, we welcome pull requests, bug fixes and issue reports. 
 
-Before proposing a change, please discuss your change by raising an issue.
+Before sending a PR, please discuss your change by raising an issue.

+# Changelog
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.6.0] - 2020-02-24
+### Changed
+- Drop library dependency on `golang.org/x/{lint, tools}`.
+
+## [1.5.1] - 2019-11-19
+- Fix bug where `Bool.CAS` and `Bool.Toggle` do work correctly together
+  causing `CAS` to fail even though the old value matches.
+
+## [1.5.0] - 2019-10-29
+### Changed
+- With Go modules, only the `go.uber.org/atomic` import path is supported now.
+  If you need to use the old import path, please add a `replace` directive to
+  your `go.mod`.
+
+## [1.4.0] - 2019-05-01
+### Added
+ - Add `atomic.Error` type for atomic operations on `error` values.
+
+## [1.3.2] - 2018-05-02
+### Added
+- Add `atomic.Duration` type for atomic operations on `time.Duration` values.
+
+## [1.3.1] - 2017-11-14
+### Fixed
+- Revert optimization for `atomic.String.Store("")` which caused data races.
+
+## [1.3.0] - 2017-11-13
+### Added
+- Add `atomic.Bool.CAS` for compare-and-swap semantics on bools.
+
+### Changed
+- Optimize `atomic.String.Store("")` by avoiding an allocation.
+
+## [1.2.0] - 2017-04-12
+### Added
+- Shadow `atomic.Value` from `sync/atomic`.
+
+## [1.1.0] - 2017-03-10
+### Added
+- Add atomic `Float64` type.
+
+### Changed
+- Support new `go.uber.org/atomic` import path.
+
+## [1.0.0] - 2016-07-18
+
+- Initial release.

 Simple wrappers for primitive types to enforce atomic access.
 
 ## Installation
-`go get -u go.uber.org/atomic`
+
+```shell
+$ go get -u go.uber.org/atomic@v1
+```
+
+### Legacy Import Path
+
+As of v1.5.0, the import path `go.uber.org/atomic` is the only supported way
+of using this package. If you are using Go modules, this package will fail to
+compile with the legacy import path path `github.com/uber-go/atomic`.
+
+We recommend migrating your code to the new import path but if you're unable
+to do so, or if your dependencies are still using the old import path, you
+will have to add a `replace` directive to your `go.mod` file downgrading the
+legacy import path to an older version.
+
+```
+replace github.com/uber-go/atomic => github.com/uber-go/atomic v1.4.0
+```
+
+You can do so automatically by running the following command.
+
+```shell
+$ go mod edit -replace github.com/uber-go/atomic=github.com/uber-go/atomic@v1.4.0
+```
 
 ## Usage
+
 The standard library's `sync/atomic` is powerful, but it's easy to forget which
 variables must be accessed atomically. `go.uber.org/atomic` preserves all the
 functionality of the standard library, but wraps the primitive types to

 # Changelog
 
+## 1.15.0 (23 Apr 2020)
+
+Bugfixes:
+* [#804][]: Fix handling of `Time` values out of `UnixNano` range.
+* [#812][]: Fix `IncreaseLevel` being reset after a call to `With`.  
+
+Enhancements:
+* [#806][]: Add `WithCaller` option to supersede the `AddCaller` option. This
+  allows disabling annotation of log entries with caller information if
+  previously enabled with `AddCaller`.
+* [#813][]: Deprecate `NewSampler` constructor in favor of 
+  `NewSamplerWithOptions` which supports a `SamplerHook` option. This option
+   adds support for monitoring sampling decisions through a hook.
+
+Thanks to @danielbprice for their contributions to this release.
+
+## 1.14.1 (14 Mar 2020)
+
+Bugfixes:
+* [#791][]: Fix panic on attempting to build a logger with an invalid Config.
+* [#795][]: Vendoring Zap with `go mod vendor` no longer includes Zap's
+  development-time dependencies.
+* [#799][]: Fix issue introduced in 1.14.0 that caused invalid JSON output to
+  be generated for arrays of `time.Time` objects when using string-based time
+  formats.
+
+Thanks to @YashishDua for their contributions to this release.
+
+## 1.14.0 (20 Feb 2020)
+
+Enhancements:
+* [#771][]: Optimize calls for disabled log levels.
+* [#773][]: Add millisecond duration encoder.
+* [#775][]: Add option to increase the level of a logger.
+* [#786][]: Optimize time formatters using `Time.AppendFormat` where possible.
+
+Thanks to @caibirdme for their contributions to this release.
+
+## 1.13.0 (13 Nov 2019)
+
+Enhancements:
+* [#758][]: Add `Intp`, `Stringp`, and other similar `*p` field constructors
+  to log pointers to primitives with support for `nil` values.
+
+Thanks to @jbizzle for their contributions to this release.
+
+## 1.12.0 (29 Oct 2019)
+
+Enhancements:
+* [#751][]: Migrate to Go modules.
+
+## 1.11.0 (21 Oct 2019)
+
+Enhancements:
+* [#725][]: Add `zapcore.OmitKey` to omit keys in an `EncoderConfig`.
+* [#736][]: Add `RFC3339` and `RFC3339Nano` time encoders.
+
+Thanks to @juicemia, @uhthomas for their contributions to this release.

+// Package language implements BCP 47 language tags and related functionality.
+//
+// The most important function of package language is to match a list of
+// user-preferred languages to a list of supported languages.
+// It alleviates the developer of dealing with the complexity of this process
+// and provides the user with the best experience
+// (see https://blog.golang.org/matchlang).
+//
+//
+// Matching preferred against supported languages
+//
+// A Matcher for an application that supports English, Australian English,
+// Danish, and standard Mandarin can be created as follows:
+//
+//    var matcher = language.NewMatcher([]language.Tag{
+//        language.English,   // The first language is used as fallback.
+//        language.MustParse("en-AU"),
+//        language.Danish,
+//        language.Chinese,
+//    })
+//
+// This list of supported languages is typically implied by the languages for
+// which there exists translations of the user interface.
+//
+// User-preferred languages usually come as a comma-separated list of BCP 47
+// language tags.
+// The MatchString finds best matches for such strings:
+//
+//    handler(w http.ResponseWriter, r *http.Request) {
+//        lang, _ := r.Cookie("lang")
+//        accept := r.Header.Get("Accept-Language")
+//        tag, _ := language.MatchStrings(matcher, lang.String(), accept)
+//
+//        // tag should now be used for the initialization of any
+//        // locale-specific service.
+//    }
+//
+// The Matcher's Match method can be used to match Tags directly.
+//
+// Matchers are aware of the intricacies of equivalence between languages, such
+// as deprecated subtags, legacy tags, macro languages, mutual
+// intelligibility between scripts and languages, and transparently passing
+// BCP 47 user configuration.
+// For instance, it will know that a reader of Bokmål Danish can read Norwegian
+// and will know that Cantonese ("yue") is a good match for "zh-HK".
+//
+//
+// Using match results
+//
+// To guarantee a consistent user experience to the user it is important to
+// use the same language tag for the selection of any locale-specific services.
+// For example, it is utterly confusing to substitute spelled-out numbers
+// or dates in one language in text of another language.
+// More subtly confusing is using the wrong sorting order or casing
+// algorithm for a certain language.
+//
+//    All the packages in x/text that provide locale-specific services
+//    (e.g. collate, cases) should be initialized with the tag that was
+//    obtained at the start of an interaction with the user.
+//
+// Note that Tag that is returned by Match and MatchString may differ from any
+// of the supported languages, as it may contain carried over settings from
+// the user tags.
+// This may be inconvenient when your application has some additional
+// locale-specific data for your supported languages.
+// Match and MatchString both return the index of the matched supported tag
+// to simplify associating such data with the matched tag.
+//
+//
+// Canonicalization
+//
+// If one uses the Matcher to compare languages one does not need to
+// worry about canonicalization.
+//
+// The meaning of a Tag varies per application. The language package
+// therefore delays canonicalization and preserves information as much
+// as possible. The Matcher, however, will always take into account that
+// two different tags may represent the same language.
+//
+// By default, only legacy and deprecated tags are converted into their
+// canonical equivalent. All other information is preserved. This approach makes
+// the confidence scores more accurate and allows matchers to distinguish
+// between variants that are otherwise lost.
+//
+// As a consequence, two tags that should be treated as identical according to
+// BCP 47 or CLDR, like "en-Latn" and "en", will be represented differently. The
+// Matcher handles such distinctions, though, and is aware of the
+// equivalence relations. The CanonType type can be used to alter the
+// canonicalization form.

+// Tag Matching
+// CLDR defines an algorithm for finding the best match between two sets of language
+// tags. The basic algorithm defines how to score a possible match and then find
+// the match with the best score
+// (see https://www.unicode.org/reports/tr35/#LanguageMatching).
+// Using scoring has several disadvantages. The scoring obfuscates the importance of
+// the various factors considered, making the algorithm harder to understand. Using
+// scoring also requires the full score to be computed for each pair of tags.
+//
+// We will use a different algorithm which aims to have the following properties:
+// - clarity on the precedence of the various selection factors, and
+// - improved performance by allowing early termination of a comparison.
+//
+// Matching algorithm (overview)
+// Input:
+//   - supported: a set of supported tags
+//   - default:   the default tag to return in case there is no match
+//   - desired:   list of desired tags, ordered by preference, starting with
+//                the most-preferred.
+//
+// Algorithm:
+//   1) Set the best match to the lowest confidence level
+//   2) For each tag in "desired":
+//     a) For each tag in "supported":
+//        1) compute the match between the two tags.
+//        2) if the match is better than the previous best match, replace it
+//           with the new match. (see next section)
+//     b) if the current best match is Exact and pin is true the result will be
+//        frozen to the language found thusfar, although better matches may
+//        still be found for the same language.
+//   3) If the best match so far is below a certain threshold, return "default".
+//
+// Ranking:
+// We use two phases to determine whether one pair of tags are a better match
+// than another pair of tags. First, we determine a rough confidence level. If the
+// levels are different, the one with the highest confidence wins.
+// Second, if the rough confidence levels are identical, we use a set of tie-breaker
+// rules.
+//
+// The confidence level of matching a pair of tags is determined by finding the
+// lowest confidence level of any matches of the corresponding subtags (the
+// result is deemed as good as its weakest link).
+// We define the following levels:
+//   Exact    - An exact match of a subtag, before adding likely subtags.
+//   MaxExact - An exact match of a subtag, after adding likely subtags.
+//              [See Note 2].
+//   High     - High level of mutual intelligibility between different subtag
+//              variants.
+//   Low      - Low level of mutual intelligibility between different subtag
+//              variants.
+//   No       - No mutual intelligibility.
+//
+// The following levels can occur for each type of subtag:
+//   Base:    Exact, MaxExact, High, Low, No
+//   Script:  Exact, MaxExact [see Note 3], Low, No
+//   Region:  Exact, MaxExact, High
+//   Variant: Exact, High
+//   Private: Exact, No
+//
+// Any result with a confidence level of Low or higher is deemed a possible match.
+// Once a desired tag matches any of the supported tags with a level of MaxExact
+// or higher, the next desired tag is not considered (see Step 2.b).
+// Note that CLDR provides languageMatching data that defines close equivalence
+// classes for base languages, scripts and regions.
+//
+// Tie-breaking
+// If we get the same confidence level for two matches, we apply a sequence of
+// tie-breaking rules. The first that succeeds defines the result. The rules are
+// applied in the following order.
+//   1) Original language was defined and was identical.
+//   2) Original region was defined and was identical.
+//   3) Distance between two maximized regions was the smallest.
+//   4) Original script was defined and was identical.
+//   5) Distance from want tag to have tag using the parent relation [see Note 5.]
+// If there is still no winner after these rules are applied, the first match
+// found wins.
+//
+// Notes:
+// [2] In practice, as matching of Exact is done in a separate phase from
+//     matching the other levels, we reuse the Exact level to mean MaxExact in
+//     the second phase. As a consequence, we only need the levels defined by
+//     the Confidence type. The MaxExact confidence level is mapped to High in
+//     the public API.
+// [3] We do not differentiate between maximized script values that were derived
+//     from suppressScript versus most likely tag data. We determined that in
+//     ranking the two, one ranks just after the other. Moreover, the two cannot
+//     occur concurrently. As a consequence, they are identical for practical
+//     purposes.
+// [4] In case of deprecated, macro-equivalents and legacy mappings, we assign
+//     the MaxExact level to allow iw vs he to still be a closer match than
+//     en-AU vs en-US, for example.
+// [5] In CLDR a locale inherits fields that are unspecified for this locale
+//     from its parent. Therefore, if a locale is a parent of another locale,
+//     it is a strong measure for closeness, especially when no other tie
+//     breaker rule applies. One could also argue it is inconsistent, for
+//     example, when pt-AO matches pt (which CLDR equates with pt-BR), even
+//     though its parent is pt-PT according to the inheritance rules.
+//
+// Implementation Details:
+// There are several performance considerations worth pointing out. Most notably,
+// we preprocess as much as possible (within reason) at the time of creation of a
+// matcher. This includes:
+//   - creating a per-language map, which includes data for the raw base language
+//     and its canonicalized variant (if applicable),
+//   - expanding entries for the equivalence classes defined in CLDR's
+//     languageMatch data.
+// The per-language map ensures that typically only a very small number of tags
+// need to be considered. The pre-expansion of canonicalized subtags and
+// equivalence classes reduces the amount of map lookups that need to be done at
+// runtime.
+

+//
+// However, representing a tree as Go literals is difficult to simply do in a
+// space and time efficient way. Thus, we store them as a flattened list of
+// objects where the serialization order from the tree-based form is important.
+//
+// The "flattened ordering" is defined as a tree traversal of all enum, message,
+// extension, and service declarations using the following algorithm:

+//		for m in md.Messages:   yield m
+//		for x in md.Extensions: yield x
+//		for m in md.Messages:   yield from VisitMessageDecls(m)

+// that children themselves may have.

+// in an allocation-free way without needing to have a shadow Go type generated
+// for every message type. This technique only works using unsafe.
+//
+//
+// Example generated code:
+//
+//	type M struct {
+//		state protoimpl.MessageState
+//
+//		Field1 int32
+//		Field2 string
+//		Field3 *BarMessage
+//		...

+//			if ms.LoadMessageInfo() == nil {
+//				ms.StoreMessageInfo(mi)
+//			}
+//			return ms
+//		}
+//		return mi.MessageOf(m)
+//	}
+//
+// The MessageState type holds a *MessageInfo, which must be atomically set to
+// the message info associated with a given message instance.
+// By unsafely converting a *M into a *MessageState, the MessageState object
+// has access to all the information needed to implement protobuf reflection.
+// It has access to the message info as its first field, and a pointer to the
+// MessageState is identical to a pointer to the concrete message value.
+//
+//
+// Requirements:
+//	• The type M must implement protoreflect.ProtoMessage.
+//	• The address of m must not be nil.
+//	• The address of m and the address of m.state must be equal,
+//	even though they are different Go types.

+// Binary serialization
+//
+// This package contains functions to convert to and from the wire format,
+// an efficient binary serialization of protocol buffers.
+//
+// • Size reports the size of a message in the wire format.
+//
+// • Marshal converts a message to the wire format.
+// The MarshalOptions type provides more control over wire marshaling.
+//
+// • Unmarshal converts a message from the wire format.
+// The UnmarshalOptions type provides more control over wire unmarshaling.
+//
+//
+// Basic message operations
+//
+// • Clone makes a deep copy of a message.
+//
+// • Merge merges the content of a message into another.
+//
+// • Equal compares two messages. For more control over comparisons
+// and detailed reporting of differences, see package
+// "google.golang.org/protobuf/testing/protocmp".
+//
+// • Reset clears the content of a message.
+//
+// • CheckInitialized reports whether all required fields in a message are set.
+//
+//
+// Optional scalar constructors
+//
+// The API for some generated messages represents optional scalar fields
+// as pointers to a value. For example, an optional string field has the
+// Go type *string.
+//
+// • Bool, Int32, Int64, Uint32, Uint64, Float32, Float64, and String
+// take a value and return a pointer to a new instance of it,
+// to simplify construction of optional field values.
+//
+// Generated enum types usually have an Enum method which performs the
+// same operation.
+//
+// Optional scalar fields are only supported in proto2.
+//
+//
+// Extension accessors
+//
+// • HasExtension, GetExtension, SetExtension, and ClearExtension
+// access extension field values in a protocol buffer message.
+//
+// Extension fields are only supported in proto2.
+//
+//
+// Related packages
+//
+// • Package "google.golang.org/protobuf/encoding/protojson" converts messages to
+// and from JSON.
+//
+// • Package "google.golang.org/protobuf/encoding/prototext" converts messages to
+// and from the text format.
+//
+// • Package "google.golang.org/protobuf/reflect/protoreflect" provides a
+// reflection interface for protocol buffer data types.
+//
+// • Package "google.golang.org/protobuf/testing/protocmp" provides features
+// to compare protocol buffer messages with the "github.com/google/go-cmp/cmp"
+// package.
+//
+// • Package "google.golang.org/protobuf/types/dynamicpb" provides a dynamic
+// message type, suitable for working with messages where the protocol buffer
+// type is only known at runtime.
+//
+// This module contains additional packages for more specialized use cases.
+// Consult the individual package documentation for details.

+// Package protoreflect provides interfaces to dynamically manipulate messages.
+//
+// This package includes type descriptors which describe the structure of types
+// defined in proto source files and value interfaces which provide the
+// ability to examine and manipulate the contents of messages.
+//
+//
+// Protocol Buffer Descriptors
+//
+// Protobuf descriptors (e.g., EnumDescriptor or MessageDescriptor)
+// are immutable objects that represent protobuf type information.
+// They are wrappers around the messages declared in descriptor.proto.
+// Protobuf descriptors alone lack any information regarding Go types.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Descriptor and ProtoReflect.Descriptor accessors respectively
+// return the protobuf descriptor for the values.
+//
+// The protobuf descriptor interfaces are not meant to be implemented by
+// user code since they might need to be extended in the future to support
+// additions to the protobuf language.
+// The "google.golang.org/protobuf/reflect/protodesc" package converts between
+// google.protobuf.DescriptorProto messages and protobuf descriptors.
+//
+//
+// Go Type Descriptors
+//
+// A type descriptor (e.g., EnumType or MessageType) is a constructor for
+// a concrete Go type that represents the associated protobuf descriptor.
+// There is commonly a one-to-one relationship between protobuf descriptors and
+// Go type descriptors, but it can potentially be a one-to-many relationship.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Type and ProtoReflect.Type accessors respectively
+// return the protobuf descriptor for the values.
+//
+// The "google.golang.org/protobuf/types/dynamicpb" package can be used to
+// create Go type descriptors from protobuf descriptors.
+//
+//
+// Value Interfaces
+//
+// The Enum and Message interfaces provide a reflective view over an
+// enum or message instance. For enums, it provides the ability to retrieve
+// the enum value number for any concrete enum type. For messages, it provides
+// the ability to access or manipulate fields of the message.
+//
+// To convert a proto.Message to a protoreflect.Message, use the
+// former's ProtoReflect method. Since the ProtoReflect method is new to the
+// v2 message interface, it may not be present on older message implementations.
+// The "github.com/golang/protobuf/proto".MessageReflect function can be used
+// to obtain a reflective view on older messages.
+//
+//
+// Relationships
+//
+// The following diagrams demonstrate the relationships between
+// various types declared in this package.

+	// Let's look at just the field definition:

+	//   a       bc     de  f  ghi

+	//   [a,i)  [ 4, 0, 2, 0 ]     The whole field definition.
+	//   [a,b)  [ 4, 0, 2, 0, 4 ]  The label (optional).

+	//   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
+	//
+	// Notes:
+	// - A location may refer to a repeated field itself (i.e. not to any
+	//   particular index within it).  This is used whenever a set of elements are
+	//   logically enclosed in a single code segment.  For example, an entire
+	//   extend block (possibly containing multiple extension definitions) will
+	//   have an outer location whose path refers to the "extensions" repeated
+	//   field without an index.
+	// - Multiple locations may have the same path.  This happens when a single
+	//   logical declaration is spread out across multiple places.  The most
+	//   obvious example is the "extend" block again -- there may be multiple
+	//   extend blocks in the same scope, each of which will have the same path.
+	// - A location's span is not always a subset of its parent's span.  For
+	//   example, the "extendee" of an extension declaration appears at the
+	//   beginning of the "extend" block and is shared by all extensions within
+	//   the block.
+	// - Just because a location's span is a subset of some other location's span
+	//   does not mean that it is a descendant.  For example, a "group" defines
+	//   both a type and a field in a single declaration.  Thus, the locations
+	//   corresponding to the type and field and their components will overlap.
+	// - Code which tries to interpret locations should probably be designed to
+	//   ignore those that it doesn't understand, as more types of locations could
+	//   be recorded in the future.
