[−][src]Struct async_io::Timer
A timer that expires after a duration of time.
Timers are futures that output the Instant
at which they fired.
Examples
Sleep for 1 second:
use async_io::Timer; use std::time::Duration; async fn sleep(dur: Duration) { Timer::new(dur).await; } sleep(Duration::from_secs(1)).await;
Implementations
impl Timer
[src]
pub fn new(dur: Duration) -> Timerⓘ
[src]
Creates a timer that expires after the given duration of time.
Examples
use async_io::Timer; use std::time::Duration; Timer::new(Duration::from_secs(1)).await;
pub fn reset(&mut self, dur: Duration)
[src]
Resets the timer to expire after the new duration of time.
Note that resetting a timer is different from creating a new timer because
reset()
does not remove the waker associated with the task that is
polling the timer.
Examples
use async_io::Timer; use std::time::Duration; let mut t = Timer::new(Duration::from_secs(1)); t.reset(Duration::from_millis(100));
