std::list::assign_range(3) C++ Standard Libary std::list::assign_range(3) NAME std::list::assign_range - std::list::assign_range Synopsis template< container-compatible-range<T> R > (since C++23) void assign_range( R&& rg ); Replaces elements in the container with a copy of each element in rg. Invalidates all iterators, pointers and references to the elements. Each iterator in the range rg is dereferenced exactly once. The behavior is undefined if rg overlaps with the container. Parameters rg - an input_range with reference type convertible to the element type of the container Type requirements - std::assignable_from<T&, ranges::range_reference_t<R>> must be mod- eled. Otherwise, the program is ill-formed. - T must be EmplaceConstructible into the container from *ranges::be- gin(rg). Otherwise, the behavior is undefined. Return value (none) Notes Feature-test macro Value Std Feature __cpp_lib_containers_ranges 202202L (C++23) Ranges-aware construc- tion and insertion Example // Run this code #include <algorithm> #include <cassert> #include <list> #include <vector> int main() { const auto source = std::vector{2, 7, 1}; auto destination = std::list{3, 1, 4}; #ifdef __cpp_lib_containers_ranges destination.assign_range(source); #else destination.assign(source.cbegin(), source.cend()); #endif assert(std::ranges::equal(source, destination)); } See also insert_range inserts a range of elements (C++23) (public member function) prepend_range adds a range of elements to the beginning (C++23) (public member function) append_range adds a range of elements to the end (C++23) (public member function) assign assigns values to the container (public member function) http://cppreference.com 2024.06.10 std::list::assign_range(3)
