# futures-timer
[![Build Status](https://travis-ci.org/alexcrichton/futures-timer.svg?branch=master)](https://travis-ci.org/alexcrichton/futures-timer)
[Documentation](https://docs.rs/futures-timer)
A library for working with timers, timeouts, and intervals with the `futures`
crate.
```toml
# Cargo.toml
[dependencies]
futures-timer = "0.1"
```
An example of using a `Delay` is:
```rust
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`:
```rust
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
```rust
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));
}
```
