Types

type ErrNotUdp

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

func (ErrNotUdp) Error

func (e ErrNotUdp) Error() string

type TunnelMessage

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

/ For UDP we need to convey additional info - so put a header in the packet that goes down the tunnel

func NewTunnelMessage

func NewTunnelMessage(bufsize int) *TunnelMessage

func (*TunnelMessage) Read

func (t *TunnelMessage) Read(data []byte) (msgdata []byte, needmore bool, addr *net.UDPAddr, nextmsgoffset int, err error)

// If need more is set, read in more data and pass this current data + the new data in again

func (*TunnelMessage) Write

func (t *TunnelMessage) Write(data []byte, from *net.UDPAddr) (fullmsg []byte)
