Crate squeue

Squeue is a sized queue.

This is just a simple wrapper over a standard Rust VecDeque.

Examples

Basic queue:

use squeue::Queue;

let mut queue: Queue<usize> = Queue::new(3);
assert_eq!(None, queue.push(1));
assert_eq!(None, queue.push(2));
assert_eq!(None, queue.push(3));
assert_eq!(Some(1), queue.push(4));
assert_eq!(3, queue.len());

Thread-safe queue:

use squeue::SyncQueue;
use std::thread;

let queue: SyncQueue<&str> = SyncQueue::new(50);

let queue1 = queue.clone();
let handle1 = thread::spawn(move || queue1.push("x"));
let queue2 = queue.clone();
let handle2 = thread::spawn(move || queue2.push("y"));

handle1.join().unwrap();
handle2.join().unwrap();

assert_eq!(2, queue.len());

Structs
