name: unagi-chan
description: This library provides implementations of concurrent FIFO queues (for both
general boxed and primitive unboxed values) that are fast, perform well
under contention, and offer a Chan-like interface. The library may be of
limited usefulness outside of x86 architectures where the fetch-and-add
instruction is not available.

We export several variations of our design; some support additional
functionality while others try for lower latency by removing features or
making them more restrictive (e.g. in the Unboxed variants).

Unagi: a general-purpose near drop-in replacement for Chan.

Unagi.Unboxed: like Unagi but specialized for primitive types; this
may perform better if a queue grows very large.

Unagi.Bounded: a bounded variant with blocking and non-blocking writes,
and other functionality where a notion of the queue&#39;s capacity is
required.

Unagi.NoBlocking: lowest latency implementations for when blocking
reads aren&#39;t required.

Unagi.NoBlocking.Unboxed: like Unagi.NoBlocking but for primitive
types.

Some of these may be deprecated in the future if they are found to provide
little performance benefit, or no unique features; you should benchmark and
experiment with them for your use cases, and please submit pull requests
for additions to the benchmark suite that reflect what you find.

Here is an example benchmark measuring the time taken to concurrently write
and read 100,000 messages, with work divided amongst increasing number of
readers and writers, comparing against the top-performing queues in the
standard libraries. The inset graph shows a zoomed-in view on the
implementations here.
