Example

extern crate scoped_stateful_threadpool;
use scoped_stateful_threadpool::Pool;

fn main() {
    // Create a threadpool holding 4 threads
    let mut pool = Pool::new(4, &|| 0);

    let mut vec = vec![0, 1, 2, 3, 4, 5, 6, 7];

    // Use the threads as scoped threads that can
    // reference anything outside this closure
    pool.scoped(|scoped| {
        // Create references to each element in the vector ...
        for e in &mut vec {
            // ... and add 1 to it in a seperate thread
            scoped.execute(move |state| {
                *state += 1; // I can change the state
                *e += 1;
            });
        }
    });

    assert_eq!(vec, vec![1, 2, 3, 4, 5, 6, 7, 8]);
