[−][src]Function tokio::time::delay_for
pub fn delay_for(duration: Duration) -> Delayⓘ
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"); }
