In C++, templates enable generic programming by allowing functions and classes to operate on different data types without sacrificing type safety. Defined using the template keyword, they let developers write reusable, type-agnostic code, such as functions (e.g., template max(T a, T b)) or classes (e.g., std::vector), where the type T is specified at … Continue reading C++20 concepts for nicer compiler errors
I haven’t tried it out yet, so does it tell which constraint was not satisfied? Otherwise that’s one more unnecessary guess work.
But as usual the syntax is still way too verbose and obtuse.
