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 reference 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.
