Introduction (required): Title and brief overview of what the poster reports on. Title: Pipeline architectures in C++: overloaded pipe operator | std::expected and its monadic operations Brief programmers. One of its most characteristic patterns is composition of functions in the form of a pipeline pattern. Since C++20 we can use the ranges library with its characteristic function composition abilities thanks to 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

it is effectively computing the same lockfile that existed before. It is also possible, and a CI pipeline could do it, to directly check that libb/1.1 is defined inside the new lockfiles. If it is not there "host", "2"]], # Fourth level libd [["app1/0.1@user/testing", "3bf2...5188", "host", "1"]] ] Every item in the outer list is a “level” in the graph, a set of packages that needs to be built, and are independent built and so on. In this example, once the build of liba/0.1@user/testing finishes, as it is the only item in the first level, the second level can start, and it can build both libb/0.1@user/testing and libc/0
