std::unorde...insert_range(3) C++ Standard Libarystd::unorde...insert_range(3) NAME std::unordered_multiset::insert_range - std::unordered_multiset::in- sert_range Synopsis template< container-compatible-range<value_type> R > (since C++23) void insert_range( R&& rg ); Inserts a copy of each element in the range rg. Each iterator in the range rg is dereferenced exactly once. The be- havior is undefined if rg overlaps with the container. If after the operation the new number of elements is greater than old max_load_factor() * bucket_count() a rehashing takes place. If rehashing occurs (due to the insertion), all iterators are inval- idated. Otherwise (no rehashing), iterators are not invalidated. Parameters rg - a container compatible range, that is, an input_range whose elements are convertible to T Type requirements - value_type must be EmplaceConstructible into unordered_multiset from *ranges::begin(rg). Otherwise, the behavior is undefined. Return value (none) Complexity Average case O(N), where N is ranges::distance(rg), worst case O(N(a.size() + 1)).
