+//! 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.
