task_queue

The implementation of the thread pool for Rust Library supports dynamic control over the number of threads

extern crate task_queue;
use std::sync::{ Arc, Mutex };

let data = Arc::new(Mutex::new(0));
let mut queue = task_queue::TaskQueue::new();

for _ in 0..1000 {
  let clone = data.clone();

  queue.enqueue(move || {
      let mut guard = clone.lock().unwrap();
      *guard += 1;
  }).unwrap();
}

let not_executed_tasks = queue.stop().unwrap();
for t in &not_executed_tasks {
   t.run();
}
