easy-parallel

Easy parallel closures.

This is a simple primitive for spawning threads in bulk and waiting for them to complete. Threads are allowed to borrow local variables from the main thread.

Examples

Run two threads that increment a number:

use easy_parallel::Parallel;
use std::sync::Mutex;

let mut m = Mutex::new(0);

Parallel::new()
    .add(|| *m.lock().unwrap() += 1)
    .add(|| *m.lock().unwrap() += 1)
    .run();

assert_eq!(*m.get_mut().unwrap(), 2);

Print each number in a vector on a different thread:

use easy_parallel::Parallel;

let mut v = vec![10, 20, 30];

Parallel::new()
    .each(0..v.len(), |i| println!("{}", v[i]))
    .run();
