Still work in progress!
An example for launching a minecraft 1.12.2 client in your home directory:
fn main() {
use std::env;
use rmcll::launcher;
use rmcll::yggdrasil::{self, Authenticator};
// prepare for starting minecraft client process
let game_dir = env::home_dir().unwrap().join(".minecraft/");
let game_auth_info = yggdrasil::offline("zzzz").auth().unwrap();
let launcher = launcher::create(game_dir, game_auth_info);
let args = launcher.to_arguments("1.12.2").unwrap();
// start the 1.12.2 client now
println!("\nStarting minecraft with: {} {:?}", args.program(), args.args());
let minecraft_process = args.start().unwrap();
let output = minecraft_process.wait_with_output().unwrap();
let exit_code = output.status.code().unwrap();
println!("\nMinecraft client finished with exit code {}", exit_code);
