magic-ring-buffer vs vmcircbuf vs network-collections

A magic ring buffer (also known as a virtual ring buffer, VRB, or mirrored buffer) which is lock-free for multiple producers and a single consumer.

A circular buffer that magically wraps around without any copying

Collections suitable for use with networking, particularly when a fixed memory usage is required to prevent out-of-memory crashes. Includes two kinds of least recently used caches, a bounded hash map, a magic ring buffer (virtual ring buffer) and an arena allocator.
