Concurrent queues

Crossbeam Queue

Build Status License Cargo Documentation Rust 1.38+ chat

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.


Add this to your Cargo.toml:

crossbeam-queue = "0.3"


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.
