std::execution (“senders & receivers”) has been voted into the C++26 working draft, providing a standard framework for concurrency and parallelism in C++. However, as the community has seen many times before, simply standardizing something doesn’t imply it will be adopted, much less adopted quickly or painlessly. Now remains the problem of adopting std::execution into existing workflows, problems, and codebases.

Making this situation more challenging is the fact that std::execution as currently integrated into the C++26 working draft is a minimum viable product. Facilities that one might intuitively expect, such as networking or other I/O support, robust execution contexts, or richer primitives, are completely absent. In these early days, developers are required to implement new primitives themselves, understanding and applying the principles of std::execution to achieve higher-level goals.

This talk will consider an existing, production, networking server written using pre-C++26 established practice. It will introduce the key concepts and primitives of std::execution, and demonstrate how to extend them iteratively to ultimately replace the existing server.
