Msp (alpha)

English | 中文

WIP: Currently, it is in the alpha stage. It is functional and can be used, but configuration and feature APIs may still undergo changes between minor version releases.

A Minecraft Server Protocol client implemented in Rust that offers fast response, lightweightness, stability, comprehensive type exporting, and error feedback. It enables retrieval of server status through various protocols and returns strongly-typed JSON data.

Applicable version

Supports Java Edition and Bedrock Edition servers. The applicable version range is as follows.

• Java Edition: Suitable for server versions 1.4 and above (Protocol version number >= 47).
• Bedrock Edition: Suitable for modern Bedrock servers (1.16.220 and above).

Supported protocols

Server Information Query Protocol covering most versions, with certain protocols requiring the server to enable corresponding features.

• Server List Ping Suitable for most modern servers (1.7+).
• Netty Server Ping Suitable for servers 1.6 and later.
• Legacy Server Ping Suitable for older versions of servers (1.4 to 1.5).
• Beta Legacy Server Ping Suitable for ancient versions of servers (Beta 1.8 to 1.3).
• Ping via LAN LAN Server Discovery Protocol.
• Raknet Protocol Applicable to modern Bedrock servers.
• Query Protocol Applicable to modern Java Edition servers (available from version 1.9pre4 onwards).

Usage

1. To integrate it as a library into your own Rust project, run it in the root project directory.

cargo add msp

Or, add this dependency to your Cargo.toml file:

[dependencies]
msp = "0.1.0"

Examples

Here are some basic examples showcased below.

1. Use Conf::get_server_status to retrieve server information, return Server. Note that older versions are not supported:

use msp::{Conf, MspErr, Server};

fn main() -> Result<(), MspErr> {
    let server = Conf::create_with_port("www.example.com", 25565);
    let info: Server = server.get_server_status()?;

    println!("{}", info);

    Ok(())
}

2. Use Conf::create_with_port to create a connection configuration specifying the port:

use msp::{Conf, MspErr, Server};

fn main() -> Result<(), MspErr> {
    let server = Conf::create_with_port("www.example.com", 25565);
    let info: Server = server.get_server_status()?;

    println!("{}", info);

    Ok(())
}

3. Use get_lan_server_status to retrieve LAN online hosts:

use msp::{get_lan_server_status, MspErr, SocketConf};

fn main() -> Result<(), MspErr> {
    get_lan_server_status(&SocketConf::default())?;

    Ok(())
}

4. Use Conf::query_full to retrieve server information using the Query protocol:

use msp::{Conf, MspErr};

fn main() -> Result<(), MspErr> {
    let server = Conf::create_with_port("www.example.com", 25565);

    println!("{}", server.query_full()?);

    Ok(())
}

⚠️To use this protocol, you need to enable the enable-query option on the server side. This option can be found in the server.properties file located in the root directory. Set it as follows:

enable-query=true
query.port=25565 # Configure the port according to your specific situation

Make sure to save the changes and restart the server for the configuration to take effect.
