std::experi...DerivedFrom(3) C++ Standard Libary std::experi...DerivedFrom(3) NAME std::experimental::ranges::DerivedFrom - std::experimental::ranges::De- rivedFrom Synopsis Defined in header <experimental/ranges/concepts> template < class T, class U > concept bool DerivedFrom = (ranges TS) std::is_base_of<U, T>::value && std::is_convertible<std::remove_cv_t<T>*, std::re- move_cv_t<U>*>::value; The concept DerivedFrom<T, U> is satisfied if and only if U is a class type that is either T or a public and unambiguous base of T. Despite the use of std::is_base_of and std::is_convertible in its description above, DerivedFrom is not required to use it in its implementation. Thus, there need not be any subsumption relationship between DerivedFrom<T, U> and std::is_base_of<U,T>::value or std::is_convertible<std::re- move_cv_t<T>*, std::remove_cv_t<U>*>::value. See also is_base_of checks if a type is derived from the other type (C++11) (class template) is_convertible is_nothrow_convertible checks if a type can be converted to the other type (C++11) (class template) (C++20) http://cppreference.com 2022.07.31 std::experi...DerivedFrom(3)
