Types

type CmdType

type CmdType int32

CmdType is the Type of Command

type Message

type Message struct {
	Name    string `json:"-"`
	ID      string `json:"id"`
	Version string `json:"version"`
}

Message is the payload of the packet

func (Message) String

type Packet

type Packet struct {
	Version byte
	Type    PacketType
	Length  int32
	Payload []byte
}

Packet is the tcp packet data format | description | version | type | length | payload | | size(byte) | 1 | 1 | 4 | length | when the type is heartbeat(0x00), there is no Length and Payload field

type PacketType

type PacketType byte

PacketType raw packet type
