[−][src]Struct runtime::time::Delay
A future representing the notification that an elapsed duration has occurred.
Methods
impl Delay
[src]
pub fn new(dur: Duration) -> Self
[src]
Continue execution after the duration has passed.
Examples
use runtime::time::Delay; use std::time::{Duration, Instant}; let start = Instant::now(); let now = Delay::new(Duration::from_millis(40)).await; assert!(now - start >= Duration::from_millis(40));
pub fn new_at(at: Instant) -> Self
[src]
Continue execution after the given instant.
Examples
use runtime::time::Delay; use std::time::{Duration, Instant}; let start = Instant::now(); let now = Delay::new_at(start + Duration::from_millis(40)).await; assert!(now - start >= Duration::from_millis(40));
