Having Fun with C++ Coroutines • Michael Hava • 03/2026

Coroutines have a long history, dating back to the late 1950s. Language-level support has been added in C++20, yet their adoption is comparatively low and there is a perception of them being only necessary for asynchronous programming. This talk will start with the abstract idea of coroutines, present high-level libraries included in C++26 and go over caveats users need to be aware of when using coroutines. Afterwards we will do a deep dive into the C++ coroutine framework, implementing a high-level facility that is not already provided by the standard library.
