Modernizing Finite State Machines in C++ - Empower Simplicity & Boost Performance With std::variant

https://www.cppnow.org --- Modernizing Finite State Machines Implementation in C++ - Empower Simplicity and Boost Performance With std::variant - Amandeep Chawla - C++Now 2024 --- Finite State Machines (FSMs) are fundamental tools in computer science for modeling behavior in various systems, from software applications to hardware controllers. Traditionally, implementing FSMs in C++ involved using multiple inheritance hierarchies for representing states, events and actions along with heap-allocated objects. However, with the introduction of std::variant in modern C++, there is a compelling opportunity to revolutionize FSM design, offering simplicity, type safety, and performance improvements. In this talk, we explore how leveraging std::variant transforms FSM implementation, allowing for a more intuitive representation of states and transitions. By embracing variant-based FSMs, developers can streamline code, enhance readability, and mitigate common pitfalls associated with traditional FSM designs. Furthermore, we delve into performance considerations and showcase how std::variant facilitates efficient state management, removing need for heap allocation at all. Attendees will gain insights into the principles of FSM design, understand the benefits of adopting std::variant for FSM implementation, and learn practical strategies for incorporating modernized FSMs into their C++ projects. Whether you're a seasoned C++ developer seeking to simplify FSMs or a newcomer exploring advanced language features, this talk offers valuable perspectives on harnessing the power of std::variant to elevate FSM development to new heights. --- Slides: https://github.com/boostcon/cppnow_pr... --- Amandeep Chawla Amandeep Chawla is a seasoned software engineer with over 20 years of experience in C++.
