Reviewers wanted: Corosio & Capy (coroutine-native I/O + coroutine foundation for C++20) are entering Boost formal review
The Boost formal review of **Corosio** and **Capy** begins today (June 23) and runs through July 7. The esteemed Jeff Garland is the review manager (Jeff also managed the Boost.Asio review back in the day!).
**What these libraries are:**
* **Capy** is a coroutine foundation library providing task types, execution contexts, executors, async synchronization primitives, buffer abstractions, and coroutine composition facilities.
* **Corosio** is a coroutine-native async I/O library built on top of Capy. Networking and I/O operations are designed specifically for C++20 coroutines, including awaitable operations, executor affinity, cancellation support, and cross-platform backends (IOCP, epoll, kqueue).
Together they're a coroutine-native alternative to the callback first model. Async code reads like sync without giving up control over execution, cancellation, or performance.
**Why this review matters:** Boost currently doesn't have a coroutine-native I/O library. If these are accepted, they'd be the first.
If you have opinions about how async I/O should work in C++, now's your chance to put them on the record. Both experienced Boost contributors and first time reviewers are encouraged to participate.
