Resty

Resty is a fast and lightweight framework for concurrent and multithreadable REST APIs.

Example

#[resty::use_manual_routing]
static ROUTER: LazyLock<Router>;

#[resty::endpoint(
    Router(ROUTER),
    Path("/"),
    Method(GET),
    Header("Content-Type", "text/html; charset=utf-8")
)]
async fn get_hello_world<'a>(_req: &mut Request<'a>, res: &mut Response<'a, &'static str>) -> resty::Result {
    res.ok(&"Hello World!").await?;

    Ok(())
}

fn main() -> ExitCode {
    const ADDR: SocketAddrV4 = SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 3333);

    if let Err(error) = resty::bind::<TcpSocket>(ADDR, &ROUTER) {
        println!("{error:?}");
        return ExitCode::FAILURE;
    }
    
    println!("Listening on port 3333");

    let _: Vec<_> = std::thread::available_parallelism()
        .ok()
        .map(|n| 0..n.get())
        .unwrap_or(0..1)
        .map(|_| resty::spawn_thread())
        .collect();

    std::thread::park();

    return ExitCode::SUCCESS;
}
