magic-ring-buffer

magic-ring-buffer is a Rust crate providing 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 magic ring buffer allows 'wrap-around' of a ring buffer without the need to use two separate read or two separate writes; it exploits the fact that virtual memory does not need to be implemented using contiguous physical memory.

The current design only works on Linux-like systems, as it relies on mapping files in /dev/shm.

It should be possible to make implementations that work on Mac OS X, the BSDs and Windows.
