High-level effect handlers in C++

Effect handlers allow the programmer to implement computational effects, such as custom error handling, various forms of lightweight concurrency, and dynamic binding, inside programming language. We introduce cpp-effects, a C++ library for effect with typed high-level, object-oriented interface. demonstrate that can be successfully applied in imperative systems languages manual memory management. Through collection examples, we explore how program effectively C++, discuss intricacies challenges implementation, show despite its limitations, cpp-effects performance is competitive some cases even outperforms state-of-the-art approaches C++20 coroutines libmprompt multiprompt delimited control.
