mc-query

Implementations of Server List ping, Query, and RCON using the Minecraft networking protocol.

Maybe in the future there will be a CLI to access these features as well.

Installation

To use this library, just run cargo add mc-query.

Usage

You can read the docs here.

Examples

Using status to get basic server information

use mc_query::status;
use tokio::io::Result;

#[tokio::main]
async fn main() -> Result<()> {
    let data = status("mc.hypixel.net", 25565).await?;
    println!("{data:#?}");

    Ok(())
}

Using RconClient to run commands via RCON

use mc_query::rcon::RconClient;
use tokio::io::Result;

#[tokio::main]
async fn main() -> Result<()> {
    let mut client = RconClient::new("localhost", 25565);
    client.authenticate("supersecretrconpassword").await?;

    let response = client.run_command("time set 0").await?;
    println!("{response}");

    Ok(())
}

Using stat_basic to query the server

use mc_query::query;
use tokio;:io::Result;

#[tokio::main]
async fn main() -> Result<()> {
    let res = stat_basic("localhost", 25565).await?;
    println!(
       "Server has {} out of {} players online",
       res.num_players,
       res.max_players
    );
    
    Ok(())
}

Using stat_full to query the server

use mc_query::query;
use tokio;:io::Result;

#[tokio::main]
async fn main() -> Result<()> {
    let res = stat_full("localhost", 25565).await?;
    println!("Online players: {:#?}, res.players);
    
    Ok(())
}

Testing

Some tests in this library require a minecraft server to be running on localhost. If you are contributing a feature or bugfix that involves one of these tests, run the convienient testing script ./test (or py -3 test on Windows). You can also just run a minecraft server without the cargo tests (useful for debugging with IDEs) with ./test --server-only true.

This requires a decently modern version of Python 3, and Java 17 or higher to run the server.
