# rust-promise [![Build Status](https://travis-ci.org/lucidd/rust-promise.svg?branch=master)](https://travis-ci.org/lucidd/rust-promise)

## [Documentation](http://www.rust-ci.org/lucidd/rust-promise/doc/promise/)

## Examples

### Basics

```rust

extern crate promise;

use promise::Future;

fn main() {

    let f = Future::from_fn(proc() "hello world!");

    f.on_success(proc(value){

        println!("{}", value)

    });

    println!("end of main");

}

```

### Composing Futures

```rust

extern crate promise;

use promise::Future;

use std::time::duration::Duration;

fn main() {

    let hello = Future::delay(proc() "hello", Duration::seconds(3));

    let world = Future::from_fn(proc() "world");

    let hw = Future::all(vec![hello, world]);

    hw.map(proc(f) format!("{} {}!", f[0], f[1]))

      .on_success(proc(value){

        println!("{}", value)

    });

    println!("end of main");

}

```

```rust

extern crate promise;

use promise::Future;

use std::time::duration::Duration;

fn main() {

    let timeout = Future::delay(proc() Err("timeout"), Duration::seconds(2));

    let f = Future::delay(proc() Ok("hello world!"), Duration::seconds(3));

    let hw = Future::first_of(vec![f, timeout]);

    hw.on_success(proc(value){

        println!("{}", value)

    });

    println!("end of main");

}

```
