Struct ClientHandshake 

pub struct ClientHandshake {
    pub len: VarInt,
    pub packet_id: VarInt,
    pub protocol_version: VarInt,
    pub server_addr: String,
    pub server_port: u16,
    pub next_state: VarInt,
}

Represents the Minecraft client handshake packet.

This packet initiates the handshake with the server before status or login requests.

Example

let handshake = ClientHandshake::new("127.0.0.1".to_string(), 25565);
let bytes = handshake.to_bytes();

Fields

len: VarInt

Length of the entire packet, encoded as a VarInt.

packet_id: VarInt

Packet ID (0x00 for handshake).

protocol_version: VarInt

Protocol version number, e.g., 768 for Minecraft 1.21.

server_addr: String

Server address as a string (domain or IP).

server_port: u16

Server port number.

next_state: VarInt

Next state after handshake: 1 = status, 2 = login.

Implementations

impl ClientHandshake

pub fn new(server_addr: String, server_port: u16) -> ClientHandshake

Creates a new ClientHandshake packet for the given server address and port.

Automatically calculates packet length and uses default protocol version 768.

pub fn to_bytes(&self) -> Vec<u8>

Serializes the handshake packet into a byte vector ready for sending over the network.

The format follows Minecraft’s VarInt and packet structure conventions.

Trait Implementations

impl Debug for ClientHandshake

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
