Cancellations in Asio: a tale of coroutines and timeouts - Rubén Pérez Hidalgo

Boost.Asio is a library to build platform-independent, asynchronous networking applications in C++. It’s been around for almost 20 years, but it’s still in constant evolution. Asio includes out-of-the-box support for C++20 coroutines, making I/O programs much easier to write. It also features a powerful cancellation mechanism, called per-operation cancellation, that can be used to selectively cancel asynchronous operations. This mechanism is the heart of many powerful high-level features, like timeouts and parallel groups. This talk explores how C++20 coroutines and per-operation cancellation can be used together to solve real-world problems in the asynchronous programming world.
