std::ranges...e_view::end(3) C++ Standard Libary std::ranges...e_view::end(3) NAME std::ranges::enumerate_view::end - std::ranges::enumerate_view::end Synopsis constexpr auto end() requires (!__simple_view<V>); (1) (since C++23) constexpr auto end() const requires (2) (since C++23) /*range-with-movable-references*/<const V>; Returns an iterator or a sentinel that compares equal to the end it- erator of the enumerate_view. Let base_ denote the underlying view. 1) Equivalent to: if constexpr (ranges::forward_range<V> and ranges::common_range<V> and ranges::sized_range<V>) return /*iterator*/<false>(ranges::end(base_), ranges::dis- tance(base_)); else return /*sentinel*/<false>(ranges::end(base_)); 2) Equivalent to: if constexpr (ranges::forward_range<const V> and ranges::common_range<const V> and ranges::sized_range<const V>) return /*iterator*/<true>(ranges::end(base_), ranges::dis- tance(base_)); else return /*sentinel*/<true>(ranges::end(base_)); Parameters (none) Return value An iterator or a sentinel representing the end of the enumer- ate_view, as described above. Example This section is incomplete Reason: no example Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Cor- rect behavior ranges::distance may invoke UB for sentinel type is returned LWG 3919 C++23 sized common for such ranges non-forward underlying ranges See also begin returns an iterator to the beginning (C++23) (public member function) ranges::end returns a sentinel indicating the end of a range (C++20) (customization point object) Category: * Todo no example http://cppreference.com 2024.06.10 std::ranges...e_view::end(3)
