futures-timer's Introduction

futures-timer

A library for working with timers, timeouts, and intervals with the futures crate.

# Cargo.toml
[dependencies]
futures-timer = "0.1"

An example of using a Delay is:

extern crate futures;
extern crate futures_timer;

use std::time::Duration;

use futures::prelude::*;
use futures_timer::Delay;

fn main() {
    Delay::new(Duration::from_secs(3))
      .map(|()| println!("printed after three seconds"))
      .wait()
      .unwrap();
}

And using an Interval:

extern crate futures;
extern crate futures_timer;

use std::time::Duration;

use futures::prelude::*;
use futures_timer::Interval;

fn main() {
    Interval::new(Duration::from_secs(4))
      .take(4)
      .for_each(|()| Ok(println!("printed after three seconds")))
      .wait()
      .unwrap();
}

Or timing out a future

extern crate futures_timer;

use std::time::Duration;

use futures_timer::FutureExt;

fn main() {
    // create a future that will take at most 3 seconds to resolve
    let future = long_running_future()
      .timeout(Duration::from_secs(3));
}
