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.
