A template parameter is a special kind of parameter that can be used to pass a type as argument: Is there a way to impose a restriction on what.</p> Just like regular function parameters. Template template parameters are a powerful feature of c++ templates that allow for more flexible and reusable code. You can accept every template parameter and then check (maybe with static_assert()) that t derive from x and y template class foo { static_assert( std::is_base_of_v<x, t>. 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. For example, static_assert (is_void ::value ==. Template void myfunc1(x &var); Allows customizing the template code for a given set of template arguments. Concepts allow us to specify requirements on template arguments and perform concept checking to ensure that only compatible types are used. Second, it allows us to. It’s like having your own. Constraints inform the compiler about the capabilities a type argument must have.
