use smol_timeout::TimeoutExt;
use std::time::Duration;
let foo = async {
Timer::new(Duration::from_millis(250)).await;
24
};
let foo = foo.timeout(Duration::from_millis(100));
assert_eq!(foo.await, None);
let bar = async {
Timer::new(Duration::from_millis(100)).await;
42
};
let bar = bar.timeout(Duration::from_millis(250));
assert_eq!(bar.await, Some(42));
