A modern C++ concurrency library built on C++20 coroutines, providing tasks, executors, timers, and result objects for writing asynchronous and parallel applications. It offers high-level abstractions that replace low-level primitives like std::thread and std::mutex.

Use cases

• write async code with c++20 coroutines
• run tasks on a thread pool
• schedule delayed and periodic timers
• parallelize cpu-bound algorithms
• replace raw std::thread and mutex code
• compose concurrent tasks with when_all and when_any

When to choose

• you use C++20 and want coroutine-based concurrency
• you need executor abstractions with built-in synchronization
• you want high-level task composition instead of manual thread management

When to avoid

• you are stuck on pre-C++20 compilers
• you need GPU or heterogeneous computing concurrency
• you only need simple single-threaded async I/O already covered by your framework
