/*
Package rateio provides an io interfaces for rate-limiting.
This can be used to apply rate limiting to any type that implements an io-style interface.
For example, we can use it to restrict the reading rate of a net.Conn:
type limitedConn struct {
net.Conn
io.Reader // Our rate-limited io.Reader for net.Conn
}
func (r *limitedConn) Read(p []byte) (n int, err error) {
return r.Reader.Read(p)
}
// ReadLimitConn returns a net.Conn whose io.Reader interface is rate-limited by limiter.
func ReadLimitConn(conn net.Conn, limiter rateio.Limiter) net.Conn {
return &limitedConn{
Conn: conn,
Reader: rateio.NewReader(conn, limiter),
}
}
Then we can use ReadLimitConn to wrap our existing net.Conn and continue using
the wrapped version in its place.
