Constants

const MaxMessageLength = 1280

MaxMessageLength is the maximum length that is safe to use. TODO(ameshkov): Make it configurable.

const MinMessageLength = 100

MinMessageLength is the minimum message size. If the message is smaller, it will be padded with random bytes.

Functions

func Tunnel

func Tunnel(pipeName string, left io.ReadWriter, right io.ReadWriter)

Tunnel passes data between two connections.

Types

type MsgReadWriter

type MsgReadWriter struct {
	// contains filtered or unexported fields
}

MsgReadWriter is a wrapper over io.ReadWriter that encodes messages written to and read from the base writer.

func NewMsgReadWriter

func NewMsgReadWriter(base io.ReadWriter) (rw *MsgReadWriter)

NewMsgReadWriter creates a new instance of *MsgReadWriter.

func (*MsgReadWriter) Read

func (rw *MsgReadWriter) Read(b []byte) (n int, err error)

Read implements the io.ReadWriter interface for *MsgReadWriter.

func (*MsgReadWriter) Write

func (rw *MsgReadWriter) Write(b []byte) (n int, err error)

Write implements the io.ReadWriter interface for *MsgReadWriter.
