Coroutines Comunications. Design and Implementation Issues in C++20
Abstract
This paper explores the communication mechanisms and patterns available to coroutines to cooperate with one another. It investigates the issues in designing and implementing a framework for using C++20 coroutines effectively, for generators, asynchronous function calls, and especially asynchronous generators.
