Introduction to Sender/Receiver framework

on YouTube ↗01h 04m

" summary

Covers concrete sender/receiver primitives, shows working examples built with stdexec and NVIDIA's implementation, ties them to C++20 coroutines by mapping awaitables to senders, and implements algorithms like then, let_value, and sync_wait with a thread‑pool scheduler. Reports that std::execution (P2300) is voted in for C++26, cites libunifex running in production at scale, and demonstrates runnable examples (slides and Godbolt links) so the model and libraries actually compile and interoperate.
