Boost.Corosio is a coroutine-only I/O library for C++20 that provides asynchronous networking primitives with automatic executor affinity propagation. Every operation returns an awaitable that integrates with the IoAwaitable protocol, ensuring your coroutines resume on the correct executor without manual dispatch.
