enlfq

A simple NIF lock-free Queue using the library: moodycamel::concurrentqueue

moodycamel::ConcurrentQueue

An industrial-strength lock-free queue for C++.

Features:

• Knock-your-socks-off blazing fast performance.
• Single-header implementation. Just drop it in your project.
• Fully thread-safe lock-free queue. Use concurrently from any number of threads.
• C++11 implementation -- elements are moved (instead of copied) where possible.
• Templated, obviating the need to deal exclusively with pointers -- memory is managed for you.
• No artificial limitations on element types or maximum count.
• Memory can be allocated once up-front, or dynamically as needed.
• Fully portable (no assembly; all is done through standard C++11 primitives).
• Supports super-fast bulk operations.
• Includes a low-overhead blocking version (BlockingConcurrentQueue).
• Exception safe.

Build

$ rebar3 compile

Using

    {ok, Q} = enlfq:new().

    T =  {any, term, [], #{}, 1}.

    true = enlfq:push(Q,T).

    {ok, T} = enlfq:pop(Q).

    empty = enlfq:pop(Q).
