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 –

Returns {}. 3.4.33 PDF Processor A PDF processor provides callbacks that get called for each PDF operator handled by PDFPage process() & PDFAnnotation process() methods. The callbacks whose names start representation of ‘POD’ structs and their C++ wrapper classes. For example for fz_rect we provide these functions: std::ostream& operator<< (std::ostream& out, const fz_rect& rhs); std::ostream& operator<< (std::ostream& diagnostic each time it calls a MuPDF function (apart from keep/drop functions). If 2, we also show arg POD and pointer values. • MUPDF_trace_director If 1, generated code outputs a diagnostic when doing special
