Message Handling with Boolean Implication
summary
Message handling library for bit-layout messages uses C++20 expression templates to build matchers that the compiler simplifies using a new compile-time implies customization. The code (on GitHub, used in Intel’s compile time initialization and build library) implements Always/Never, negate and implies overloads, a dozen small simplifiers and relational rules so many matches collapse at compile time, cutting runtime dispatch work and integrating with a field-indexing library to make handlers cheap and predictable.
