[−][src]Struct runtime::time::Delay

#[must_use = "futures do nothing unless awaited"]
pub struct Delay { /* fields omitted */ }

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));
