      struct sorted_equivalent_t{explicit sorted_equivalent_t()=default;};

      inlineconstexpr sorted_equivalent_t sorted_equivalent{};

      1) The typestd::sorted_equivalent_t can be used in the function's (including constructor's) parameter list to match the intended tag.
      2) The correspondingstd::sorted_equivalent instance of(1) is a disambiguation tag that can be passed to the functions ofstd::flat_multimap andstd::flat_multiset to indicate that the input range or container is sorted (with respect to the comparator used in flat container adaptor), whilst uniqueness of elements is not required.

      [edit]Standard library

      The following standard library container adaptors use(1,2) as disambiguation tags:

      adapts two containers to provide a collection of key-value pairs, sorted by keys
      (class template)[edit]
      adapts a container to provide a collection of keys, sorted by keys
      (class template)[edit]
