std::multim...insert_range(3) C++ Standard Libarystd::multim...insert_range(3) NAME std::multimap::insert_range - std::multimap::insert_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. No iterators or references are 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 multimap from *ranges::begin(rg). Otherwise, the behavior is undefined. Return value (none) Complexity Nlog(a.size() + N), where N is ranges::distance(rg).
