Crate arraydeque

Expand description

A circular buffer with fixed capacity. Requires Rust 1.59+

It can be stored directly on the stack if needed.

This queue has O(1) amortized inserts and removals from both ends of the container. It also has O(1) indexing like a vector. The contained elements are not required to be copyable

This crate is inspired by bluss/arrayvec

Feature Flags

The arraydeque crate has the following cargo feature flags:

std
- Optional, enabled by default
- Conversions between ArrayDeque and Vec
- Use libstd

Usage

First, add the following to your Cargo.toml:

[dependencies]
arraydeque = "0.5"

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 = "0.4", default-features = false }

Behaviors

ArrayDeque provides two different behaviors, Saturating and Wrapping, determining whether to remove existing element automatically when pushing to a full deque.

See the behavior module documentation for more.
