lobby-queue

A const-size queue-like data structure.

Usage

Add lobby-queue to your Cargo.toml:

[dependencies]
lobby-queue = "0.2"

And use it:

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);
    }
}

lib.rs:

This crate provides a const-size queue-like data structure. When full, pushing new items will remove the head (first-added) items.

[dependencies]
lobby-queue = "0.2"

use lobby_queue::Lobby;

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);
}
