tagged_tuple

 
Defined in header <experimental/ranges/tuple>

using tagged_tuple = /* see below */;
(ranges TS)

Convenience alias template for naming a ranges::tagged wrapping a std::tuple.

A TaggedType is a function type S(T), where S is a TagSpecifier and T is the type of the element.

tagged_tuple<S1(T1), ..., SN(TN)> is an alias for ranges::tagged<std::tuple<T1, ..., TN>, S1, ..., SN>.

[edit] Notes

Because a function type is used to "glue" the tag specifier and the corresponding element type together, the usual parameter type adjustments apply. In particular, top-level cv-qualifiers are removed and array types are adjusted to pointers: tagged_tuple<tag::in(const int* const), tag::out(int[])> is ranges::tagged<std::tuple<const int*, int*>, tag::in, tag::out>.
