Function tokio::time::sleep

pub fn sleep(duration: Duration) -> Sleep

Waits until duration has elapsed.

Equivalent to sleep_until(Instant::now() + duration). An asynchronous analog to std::thread::sleep.

No work is performed while awaiting on the sleep future to complete. Sleep operates at millisecond granularity and should not be used for tasks that require high-resolution timers.

To run something regularly on a schedule, see interval.

The maximum duration for a sleep is 68719476734 milliseconds (approximately 2.2 years).

Cancellation

Canceling a sleep instance is done by dropping the returned future. No additional cleanup work is required.

Examples

Wait 100ms and print "100 ms have elapsed".

use tokio::time::{sleep, Duration};

#[tokio::main]
async fn main() {
    sleep(Duration::from_millis(100)).await;
    println!("100 ms have elapsed");
}
