15This crate provides concurrent queues that can be shared among threads:
16
17* [`ArrayQueue`], a bounded MPMC queue that allocates a fixed-capacity buffer on construction.
18* [`SegQueue`], an unbounded MPMC queue that allocates small buffers, segments, on demand.
19
20Everything in this crate can be used in `no_std` environments, provided that `alloc` feature is
21enabled.
