    let _window = witas::Window::builder()
        .title("witas hello")
        .inner_size(witas::LogicalSize::new(640, 480))
        .set_receiver(&rx)
        .await
        .unwrap();
    loop {
        let (event, _) = rx.recv().await;
        println!("{:?}", event);
        if let witas::Event::Closed = event {
