    let pausable = Pausable::new(async {
        let mut count = 0;
        loop {
            sleep(Duration::from_millis(300)).await;
            count += 1;
            println!("count: {}", count);
        }
    });
    let controller = pausable.controller();
    tokio::spawn(pausable);
    println!("spawn");
    sleep(Duration::from_secs(1)).await;
    controller.pause();
    println!("paused");
    sleep(Duration::from_secs(1)).await;
    controller.resume();
    println!("resumed");
    sleep(Duration::from_secs(1)).await;
