The common reference type of two tuple-like types is a std::tuple consists of the common reference types of all corresponding element type pairs of both types, where the cv and reference qualifiers on the tuple-like types are applied to their element types.
Given
-
TTypesas the pack formed by the sequence of std::tuple_element_t <i, TTuple> for every integer i in[0,std::tuple_size_v <TTuple>), and -
UTypesas the pack formed by the sequence of std::tuple_element_t <i, UTuple> for every integer i in[0,std::tuple_size_v <UTuple>),
the following constraints need to be satisfied:
-
TTupleorUTupleis a std::tuple specialization. - std::is_same_v <TTuple, std::decay_t <TTuple>> is true.
- std::is_same_v <UTuple, std::decay_t <UTuple>> is true.
- std::tuple_size_v <TTuple> equals std::tuple_size_v <UTuple> (
TTupleandUTuplehave the same number of elements). - std::tuple <std::common_reference_t <TQual<TTypes>..., UQual<UTypes>>...> denotes a type.
