Struct wait_group::WaitGroup

pub struct WaitGroup(_);

A WaitGroup waits for a collection of threads to finish. Then each of the threads runs and calls Done when finished. At the same time, Wait can be used to block until all threads have finished.

Example

use std::thread;

let wg = wait_group::WaitGroup::new();

for _ in 0..10 {
    wg.add(1);
    let wg2 = wg.clone();
    thread::spawn(move || {
        // do something

        // call done
        wg2.done();
    });
}
// block until all threads have finished
wg.wait();
