Crate futures_threadpool [] [src]

A simple crate for executing work on a thread pool, and getting back a future.

This crate provides a simple thread pool abstraction for running work externally from the current thread that's running. An instance of Future is handed back to represent that the work may be done later, and further computations can be chained along with it as well.

extern crate futures;
extern crate futures_spawn;
extern crate futures_threadpool;

use futures::Future;
use futures_spawn::SpawnHelper;
use futures_threadpool::ThreadPool;

// Create a worker thread pool with four threads
let pool = ThreadPool::new(4);

// Execute some work on the thread pool, optionally closing over data.
let a = pool.spawn(long_running_future(2));
let b = pool.spawn(long_running_future(100));

// Express some further computation once the work is completed on the thread
// pool.
let c = a.join(b).map(|(a, b)| a + b).wait().unwrap();

// Print out the result
println!("{:?}", c);
