bsl::unordered_multiset::insert_range

Insert into this unordered multiset the value of each value_type object in the specified range. The (template parameter) type RANGE must meet the requirements the C++20 standard [ranges] providing access to values of a type convertible to value_type, and value_type must be emplace‐constructible from *i into this unordered multiset, where i is a dereferenceable iterator obtained from range (see {Requirements on KEY}). The behavior is undefined if range overlaps this unordered multiset.
