Functions

func Decode

func Decode(r io.Reader) (byte, []byte, error)

Decode reads one message. Returns type and payload.

func DecodeResize

func DecodeResize(b []byte) (cols, rows uint16, err error)

DecodeResize decodes cols and rows from 4 bytes.

func Encode

func Encode(w io.Writer, typ byte, payload []byte) error

Encode writes a message: [type][2-byte big-endian length][payload]. Each call makes exactly one Write call containing the complete message. Bridge adapters (sshBridge, wsBridge) depend on this invariant.

func EncodeResize

func EncodeResize(cols, rows uint16) []byte

EncodeResize encodes cols and rows as 4 bytes.

func MarshalMsg

func MarshalMsg(typ byte, payload []byte) ([]byte, error)

MarshalMsg returns a raw proto message as bytes without writing to a stream. Used by bridge adapters that need to buffer messages before delivery.
