Readerwriterqueue
这是一个专为 C++ 设计的单生产者单消费者并发队列，用于线程间的无锁数据交换。它提供了一种无需互斥锁或锁即可传输数据的线程安全机制。
该队列实现为一个连续的循环缓冲区，支持动态容量增长，以防止队列达到上限时数据丢失。它利用原子同步和无等待索引管理来协调写入线程和读取线程之间的数据访问。
该库涵盖线程间通信和缓冲区管理，提供阻塞和非阻塞出队操作，以管理消费线程等待新数据的方式。
Features
- Single-Producer Single-Consumer Queues - Implements a specialized single-producer single-consumer model to eliminate contention and minimize synchronization overhead.
- Lock-Free Thread Communication - Provides high-performance primitives for transferring data between threads without the overhead of mutex locking.
- Thread-Safe Communication Channels - Offers a high-performance C++ data structure for safe information passing between concurrent threads.
- Circular Memory Buffers - Uses a ring-based memory layout to efficiently reuse space for data exchange between threads.
- Contiguous Memory Buffers - Allocates elements in flat, contiguous memory blocks to optimize cache locality and reduce latency.
- Lock-Free - Employs atomic primitives and memory barriers to ensure thread-safe data exchange without mutex locks.
- Buffer Capacity Growth - Supports dynamic allocation of larger contiguous blocks when the queue reaches capacity to prevent data loss.
- Wait-Free Synchronization - Manages head and tail indices using atomic integers to guarantee progress for both producer and consumer.
- Dynamic Buffer Management - Manages queue elements by combining upfront memory reservation with dynamic capacity expansion.
- Low Latency Messaging - Minimizes message delivery delay between threads by avoiding traditional mutex synchronization.
- Inter-Thread Buffer Management - Handles data streams between threads using a contiguous memory buffer that grows as demand increases.
- Blocking Synchronization - Implements mechanisms to suspend consumer threads until the producer adds new data to the queue.
- Concurrency and Parallelism - Fast single-producer single-consumer lock-free queue.
