An example of an AI chatbot conversation about error handling in C++20 templates.
How can I handle errors in C++20 templates?
In C++20, you can use concepts to enforce constraints on template parameters, which helps in error handling.
Can you give me an example of using concepts for error handling?
Sure! You can define a concept like std::integral to ensure a template only accepts integral types, providing clear error messages.
What happens if the template parameter doesn't meet the concept requirements?
If the parameter doesn't meet the requirements, the compiler will generate a static assertion error, making debugging easier.
Are there other ways to handle errors in templates?
Yes, you can also use SFINAE (Substitution Failure Is Not An Error) to provide alternative implementations based on template parameter validity.
