The Sender/Receiver Framework in C++ - Getting the Lazy Task Done

Explore the C++26 sender/receiver framework for asynchronous operations through this comprehensive conference talk from C++Now 2025. Learn how to create a coroutine task class template that works effectively with the new asynchronous vocabulary and algorithms. Discover the fundamental operation of sender/receiver aware tasks, understand the critical importance of scheduler affinity in asynchronous programming, and master allocator support for coroutine frames. Gain insights into providing environments to child operations and implementing error propagation mechanisms that don't rely on exceptions. Presented by Dietmar Kühl, a senior software developer at Bloomberg and regular contributor to the ANSI/ISO C++ standards committee, this technical presentation addresses the practical implementation challenges developers face when working with C++26's asynchronous programming model, filling the gap where the current specification lacks a matching coroutine task class template that most users would need for real-world applications.
