# tinypool-rs


***tinypool*** is a simple thread pool implementation in Rust.

A thread pool is a collection of threads that can be used to execute jobs concurrently.
The aim of this crate is to provide a simple, easy-to-use thread pool that can be used in any project.

[**Documentation**](https://docs.rs/tinypool/latest/tinypool/ "docs.rs")

[**Crate**](https://crates.io/crates/tinypool "crates.io")

### Example (1)

```rust
use tinypool::ThreadPool;
use std::sync::{Arc, Mutex};

let mut threadpool = ThreadPool::new(Some(4)).unwrap();
let counter = Arc::new(Mutex::new(0));

for _ in 0..100 {
    let counter_thrd = Arc::clone(&counter);
    threadpool.add_to_queue(move || {
        let mut counter = counter_thrd.lock().unwrap();
        *counter += 1;
    });
}

threadpool.join();
assert_eq!(*counter.lock().unwrap(), 100);
```

### Example (2)

```rust
use tinypool::ThreadPool;
use std::sync::mpsc;

let mut threadpool = ThreadPool::new(Some(4)).unwrap();
let (tx, rx) = mpsc::channel();

for i in 0..100 {
    let tx = tx.clone();
    threadpool.add_to_queue(move || tx.send(i).unwrap());
}
drop(tx);

let mut sum = 0;
while let Ok(i) = rx.recv() {
   sum += i;
}

assert_eq!(sum, 4950);
```
