//! Concurrent queues.
//!
//! 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.
