std::deque::append_range(3) C++ Standard Libary std::deque::append_range(3) NAME std::deque::append_range - std::deque::append_range Synopsis template< container-compatible-range<T> R > (since C++23) void append_range( R&& rg ); Inserts copies of elements from the range rg before end(), in non- reversing order. All iterators (including the end() iterator) are invalidated. No references are invalidated. Each iterator in rg is dereferenced exactly once. Parameters rg - a container compatible range, that is, an input_range whose elements are convertible to T Type requirements - T must be EmplaceConstructible into deque from *ranges::begin(rg). Otherwise, the behavior is undefined. Return value (none) Complexity Linear in size of rg. The number of calls to the constructor of T is exactly equal to the std::ranges::size(rg)). Exceptions If an exception is thrown other than by the copy constructor, move constructor, assignment operator, or move assignment operator of T there are no effects. If an exception is thrown while inserting a single element at either end, there are no effects. Otherwise, if an exception is thrown by the move construc- tor of a non-CopyInsertable T, the effects are unspecified.
