arraydeque

A circular buffer with fixed capacity. Requires Rust 1.20+.

This crate is inspired by bluss/arrayvec

Documentation

Usage

First, add the following to your Cargo.toml:

[dependencies]
arraydeque = "0.3"

Next, add this to your crate root:

extern crate arraydeque;

Currently arraydeque by default links to the standard library, but if you would instead like to use arraydeque in a #![no_std] situation or crate you can request this via:

[dependencies]
arraydeque = { version = "0.3", default-features = false }

Example

extern crate arraydeque;

use arraydeque::ArrayDeque;

fn main() {
    let mut deque: ArrayDeque<[_; 4]> = ArrayDeque::new();
    // capacity is always backend_array.len() - 1
    assert_eq!(deque.capacity(), 3);
    assert_eq!(deque.len(), 0);

    deque.push_back(1);
    deque.push_back(2);
    assert_eq!(deque.len(), 2);

    assert_eq!(deque.pop_front(), Some(1));
    assert_eq!(deque.pop_front(), Some(2));
    assert_eq!(deque.pop_front(), None);
}
