Introduction to Sender Receiver framework and std execution - Goran Arandelovic

Asynchronous programming in C++ is not an easy task. There are various async models and corresponding libraries which facilitate these tasks, and it seems that it's becoming easier. With C++20 coroutines we got new possibilities, but standard library support for coroutines is virtually non-existent. Also, having only C++ coroutines in a toolbox is like having only raw pointers or std::thread, i.e. low-level primitives which cannot be enough for highly composable and scalable APIs. There are a lot of libraries for async tasks implemented on top of coroutines, but there's still an open question - which one to use?
Aside from coroutines, Senders/Receivers emerged as a quite promising model for async computations and hopefully, we'll get std::execution (P2300) in C++26.
In this talk, I'll present Sender/Receiver concepts, various examples from stdexec, NVIDIA's implementation of std::execution proposal and I'll shed some light on how Sender/Receiver model interacts with C++ coroutines.

If I may ask, what was "super hot previous talk"?
