This header is part of the ranges library.

Tagged tuples

Defined in namespace std::experimental::ranges
tagged_tuple	alias template for a tagged std::tuple (alias template)
make_tagged_tuple	convenience function for creating a tagged_tuple (function template)

Synopsis

namespace std { namespace experimental { namespace ranges { inline namespace v1 {
 
template <TaggedType... Types>
using tagged_tuple = tagged<tuple</* TAGELEM */(Types)...>,
                            /* TAGSPEC */(Types)...>;
 
template <TagSpecifier... Tags, class... Types>
  requires sizeof...(Tags) == sizeof...(Types)
    constexpr /* see definition */ make_tagged_tuple(Types&&... t);
 
}}}}
