Codec constants.

Variables

var ErrPacketSizeExcced = errors.New("codec: packet size exceed")

ErrPacketSizeExcced is the error used for encode/decode.

Functions

func Encode

func Encode(typ packet.Type, data []byte) ([]byte, error)

Encode create a packet.Packet from the raw bytes slice and then encode to network bytes slice Protocol refs: https://github.com/NetEase/pomelo/wiki/Communication-Protocol

-<type>-|--------<length>--------|-<data>- --------|------------------------|-------- 1 byte packet type, 3 bytes packet data length(big end), and data segment

Types

type Decoder

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

A Decoder reads and decodes network data slice

func NewDecoder

func NewDecoder() *Decoder

NewDecoder returns a new decoder that used for decode network bytes slice.

func (*Decoder) Decode

func (c *Decoder) Decode(data []byte) ([]*packet.Packet, error)

Decode decode the network bytes slice to packet.Packet(s) TODO(Warning): shared slice
