Structured Networking in C++
summary
Demonstrates a concrete implementation of the p2300 senders/receivers model to make networking structured: coroutines build async Echo server tasks, connect returns a nonmovable operation_state and start runs it, and cancellation is omitted for the demo. Uses a simple IO context with epoll/poll style readiness, one heap job per client, and async accept/read/write adapters. The result compiles and runs: a fully asynchronous echo server that fits the core logic on a single page.
