std::experimental::ranges::DerivedFrom

Defined in header `<experimental/ranges/concepts>`
template < class T, class U > concept bool DerivedFrom = std::is_base_of<U, T>::value && std::is_convertible<std::remove_cv_t<T>, std::remove_cv_t<U>>::value;		(ranges TS)

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::remove_cv_t<T>*, std::remove_cv_t<U>*>::value.

is_base_of (C++11)	checks if a type is derived from the other type (class template) [edit]
is_convertibleis_nothrow_convertible (C++11)(C++20)	checks if a type can be converted to the other type (class template) [edit]
