A fast, wait-free single-producer single-consumer (SPSC) lock-free queue for C++11, implemented as a header-only library. It supports move semantics, dynamic growth, and a blocking variant with timed waits.

Use cases

• pass data between two threads without locks
• fast SPSC queue for C++
• lock-free producer-consumer communication
• queue that never allocates on enqueue
• high-performance inter-thread message passing
• replace std::queue in a two-thread pipeline

When to choose

• you have exactly one producer thread and one consumer thread
• you need wait-free O(1) enqueue/dequeue with minimal latency
• you want a header-only dependency with no build system required
• you need a blocking queue with timed waits

When to avoid

• you need multiple producers or multiple consumers
• threads need to switch producer/consumer roles
• you need cross-platform atomics on compilers older than C++11
• you need a general-purpose MPMC queue (use the author's moodycamel::ConcurrentQueue instead)
