std::basic_...on_reference(3) C++ Standard Libary std::basic_...on_reference(3) NAME std::basic_common_reference - std::basic_common_reference Synopsis Defined in header <utility> template< class T1, class T2, class U1, class U2, template<class> class TQual, template<class> class UQual > requires requires { typename std::pair<std::common_reference_t<TQual<T1>, UQual<U1>>, (since C++23) std::common_reference_t<TQual<T2>, UQual<U2>>>; } struct basic_common_reference<std::pair<T1, T2>, std::pair<U1, U2>, TQual, UQual>; The common reference type of two pairs is a pair of both common refer- ence types of corresponding element types of both pairs, where the cv and reference qualifiers on the pairs are applied to their element types. The common reference type is defined only if both pairs of corresponding element types have common reference types. Member types Member type Definition std::pair<std::common_reference_t<TQual<T1>, UQual<U1>>, type std::common_reference_t<TQual<T2>, UQual<U2>>> Example This section is incomplete Reason: no example See also common_reference determines the common reference type of a basic_common_reference group of types (C++20) (class template) std::basic_common_reference<tuple-like> determines the common reference type of a (C++23) tuple and a tuple-like type (class template specialization) Category: * Todo no example http://cppreference.com 2024.06.10 std::basic_...on_reference(3)
