packet

Overview ¶

Package packet provides network messaging protocol and serialization layer.

Packet can be created with shortcut:

senderAddr, _ := host.NewAddress("127.0.0.1:1337")
receiverAddr, _ := host.NewAddress("127.0.0.1:1338")

sender := host.NewHost(senderAddr)
receiver := host.NewHost(receiverAddr)

msg := packet.NewPingPacket(sender, receiver)

// do something with packet

Or with builder:

builder := packet.NewBuilder()

senderAddr, _ := host.NewAddress("127.0.0.1:1337")
receiverAddr, _ := host.NewAddress("127.0.0.1:1338")

sender := host.NewHost(senderAddr)
receiver := host.NewHost(receiverAddr)

msg := builder.
	Sender(sender).
	Receiver(receiver).
	Type(packet.TypeFindHost).
	Request(&packet.RequestDataFindHost{}).
	Build()

// do something with packet

Packet may be serialized:

msg := &packet.Packet{}
serialized, err := packet.SerializePacket(msg)

if err != nil {
	panic(err.Error())
}

fmt.Println(serialized)

And deserialized therefore:

var buffer bytes.Buffer

// Fill buffer somewhere

msg, err := packet.DeserializePacket(buffer)

if err != nil {
	panic(err.Error())
}

// do something with packet
