How can you prevent users from mistakenly instantiating your template classes with non-numerical types in a C++ library of numerical methods, leading to confusing compiler errors?
- Provide runtime type checking
- Use static_assert with type traits
- Offer detailed documentation
- Implement virtual functions
The static_assert mechanism, combined with type traits, allows for compile-time checks. By using static_assert along with type traits like std::is_arithmetic, it's possible to generate clear, intentional compiler errors if a user tries to instantiate a template with a non-numeric type, thus providing instant feedback to the user.
