# JobPool

A simple and lightweight threadpool implementation for Rust.

[![Build Status](https://travis-ci.org/darshanparajuli/jobpool.svg?branch=master)](https://travis-ci.org/darshanparajuli/jobpool)

## Example

```rust

extern crate jobpool;

use jobpool::JobPool;

use std::thread;

use std::time::Duration;

use std::sync::mpsc;

fn main() {

    let pool_size = 8; // or number of cpu cores

    let mut pool = JobPool::new(pool_size);

    // pool.auto_grow(100);

    let (tx, rx) = mpsc::channel();

    for i in 0..100 {

        let tx = tx.clone();

        pool.queue(move || {

            // Do some work, following is just for example's sake

            thread::sleep(Duration::from_millis(100));

            println!("sending: {}", i);

            tx.send(i).unwrap();

        });

        // or pool.queue_with_priority(move || {...}, priority_val);

    }

    for _ in 0..100 {

        match rx.recv() {

            Ok(val) => println!("received: {}", val),

            Err(e) => eprintln!("Error: {}", e),

        }

    }

    // Explicit call to shutdown; JobPool shuts down automatically after

    // going out of scope as well.

    pool.shutdown();

}

```
