pub fn delay_for(duration: Duration) -> DelayⓘNotable traits for Delayimpl Future for Delay type Output = ();Expand description
Waits until duration has elapsed.
Equivalent to delay_until(Instant::now() + duration). An asynchronous
analog to std::thread::sleep.
No work is performed while awaiting on the delay to complete. The delay 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 delay 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::{delay_for, Duration};
#[tokio::main]
async fn main() {
delay_for(Duration::from_millis(100)).await;
println!("100 ms have elapsed");
}
