Overview

Package reconn provides an implementation of net.Conn that allows replaying a limited amount of the data that was read from the underlying conn. This can be used to implement look aheads on top of other net.Conns.

Index

• Variables
• type Conn
  • func Wrap(conn net.Conn, limit int) *Conn
  • func (conn *Conn) Read(b []byte) (n int, err error)
  • func (conn *Conn) Rereader() (io.Reader, error)

Variables

var ErrOverflowed = errors.New("replay buffer overflowed")

Types

type Conn

type Conn struct {
	net.Conn
	// contains filtered or unexported fields
}

Conn is a net.Conn that supports replaying.

func Wrap

func Wrap(conn net.Conn, limit int) *Conn

Wrap wraps the supplied conn, allowing replay from the current point up to the given limit.

func (*Conn) Read

func (conn *Conn) Read(b []byte) (n int, err error)

Read implements the method from net.Conn with added support for replaying.

func (*Conn) Rereader

func (conn *Conn) Rereader() (io.Reader, error)

Rereader returns an io.Reader that reads from the last marked point. If the connection has overflowed, this returns an error.
