1) The type
std::sorted_equivalent_t can be used in the function's (including constructor's) parameter list to match the intended tag.2) The corresponding
std::sorted_equivalent instance of (1) is a disambiguation tag that can be passed to the functions of std::flat_multimap and std::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.Standard library
The following standard library container adaptors use (1,2) as disambiguation tags:
| (哋它亢++23) |
adapts two containers to provide a collection of key-value pairs, sorted by keys (class template) |
| (哋它亢++23) |
adapts a container to provide a collection of keys, sorted by keys (class template) |
