# Crossbeam Queue
[](https://discord.com/invite/JXYwgWZ)
This crate provides concurrent queues that can be shared among threads:
* [`ArrayQueue`], a bounded MPMC queue that allocates a fixed-capacity buffer on construction.
* [`SegQueue`], an unbounded MPMC queue that allocates small buffers, segments, on demand.
Everything in this crate can be used in `no_std` environments, provided that `alloc` feature is
enabled.
## Usage
Add this to your `Cargo.toml`:
```toml
[dependencies]
crossbeam-queue = "0.3"
```
## Compatibility
Crossbeam Queue supports stable Rust releases going back at least six months,
and every time the minimum supported Rust version is increased, a new minor
version is released. Currently, the minimum supported Rust version is 1.38.
