# lobby-queue

A const-size queue-like data structure.

## Usage

Add lobby-queue to your `Cargo.toml`:

``` toml
[dependencies]
lobby-queue = "0.2"
```

And use it:

``` rust
use lobby_queue::Lobby;

fn main() {
    let mut m = Lobby::new([None, None, None]);

    m.push(0);
    m.push(1);
    m.push(2);
    assert_eq!(Some(&0), m.first());

    let v0 = m.push(3);
    assert_eq!(Some(0), v0);
    assert_eq!(Some(&1), m.first());

    for v in m {
        println!("{}", v);
    }
}
```
