Lightning Talk: Powered by C++20 Meta-Programming (MP)
summary
Claims a complete C++20 state machine implemented with template meta‑programming and std::ranges, fitting on a single slide and yielding zero-overhead abstraction with fast runtime dispatch. It extracts compile‑time lists of events and states from transitions using fixed_string, transform/filter/unique, then builds per‑event per‑state mappings and a runtime jump table via an immediately invoked constexpr lambda. Implementation uses static_cast calls for actions and updates the state, and reports measurable fast completion times.
