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.
