pub fn sleep_until(deadline: Instant) -> SleepNotable traits for Sleepimpl Future for Sleep    type Output = ();
Expand description

Waits until deadline is reached.

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.

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_until, Instant, Duration};

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

See the documentation for the Sleep type for more examples.
