minecraft-client-rs

A client for the Minecraft RCON protocol.

Library Usage

// Create a new client and connect to the server.
let mut client = Client::new("127.0.0.1:25575".to_string()).unwrap();

// Send some commands.
match client.authenticate("password".to_string()) {
	Ok(_) => { },
	Err(e) => { /* handle authentication error */ },
}
match client.send_command("seed".to_string()) {
	Ok(resp) => { println!("{}", resp.body); }, // "Seed: [1871644822592853811]"
	Err(e) => { /* handle error */ },
}

// Disconnect cleanly when finished.
client.close().unwrap();
