C Allow Only Specific Types Of Template Parameters

C Allow Only Specific Types Of Template Parameters - The c++ standard library provides several predefined concepts. They play well with the template magic happening behind the scenes. You can use it as follows in your case (i.e. Std::enable_if or std::enable_if_t could be used for restricting or enabling the types used for template specialization via template parameters. If you want to check the types of the first function argument, the same approach holds, only there is no need for something like isone and istwo, you can use std::is_same_v. Consider a template function prototype like this: When we create a primary function template, we use placeholder types (technically called type template parameters, informally called template types) for any parameter types,. One way to do that is the requires clause. Or template x* myfunc2(); We either find an exact match between the function call arguments and template type parameters, or we don’t.

This will ensure that the compilation of the template. They play well with the template magic happening behind the scenes. If you really need to have specific class members depends on template args, you can wrap them in the base class and derive from specific template class using some conditions or just a. As of c++11, there is no way to constrain template type arguments. One way to do that is the requires clause. Starting with c++20, you can constrain template arguments. There are ways to restrict the types you can use inside a template you write by using specific typedefs inside your template. Or template x* myfunc2(); Template template parameters are a powerful feature of c++ templates that allow for more flexible and reusable code. You can, however, make use of sfinae to ensure that a template is only instantiated for particular types.
