Function std::thread::sleep1.4.0 [] [src]

pub fn sleep(dur: Duration)

Puts the current thread to sleep for the specified amount of time.

The thread may sleep longer than the duration specified due to scheduling specifics or platform-dependent functionality.

Platform behavior

On Unix platforms this function will not return early due to a signal being received or a spurious wakeup. Platforms which do not support nanosecond precision for sleeping will have dur rounded up to the nearest granularity of time they can sleep for.

let ten_millis = time::Duration::from_millis(10);
let now = time::Instant::now();


assert!(now.elapsed() >= ten_millis);Run
