1) The type
std::sorted_unique_t can be used in the function's (including constructor's) parameter list to match the intended tag.2) The corresponding
std::sorted_unique instance of (1) is a disambiguation tag that can be passed to the functions of std::flat_map and std::flat_set to indicate that the input range or container is sorted (with respect to the comparator used in flat container adaptor) and all elements of such container or range are unique.[edit] Standard library
The following standard library container adaptors use (1,2) as disambiguation tags:
