concurrencpp

Supports both eager and lazy coroutines with co_await, enabling non-blocking, synchronous-like code as shown in the parallel Fibonacci example, which simplifies asynchronous programming.

Provides various executor types like thread pool, background, and manual executors, allowing fine-grained control over task scheduling and execution contexts, as detailed in the executor API section.

Reduces race conditions and deadlocks by abstracting low-level threading primitives into high-level tasks with built-in synchronization, emphasizing safety and productivity as per the library philosophy.

Well-tested on various platforms and operating systems, ensuring reliability for production use, as highlighted in the README's claims of maturity and testing.
