overview of what the poster reports on. Title: Pipeline architectures in C++: overloaded pipe operator | std::expected and its monadic operations Brief overview: Functional programming in C++ is the overloaded pipe operator. In this poster I show how to implement a custom pipeline framework that employs std::expected, available since C++23. An overloaded custom pipe operator | will be presented my book about C++ [1][3]. One of the topics was to describe the behavior of the overloaded pipe operator | in std::ranges. I came across Ankur's Satle lecture [4] and decided to expand on this topic –
