std::experi...ranges::View(3) C++ Standard Libarystd::experi...ranges::View(3)

NAME
       std::experimental::ranges::View - std::experimental::ranges::View

Synopsis
	  Defined in header <experimental/ranges/range>
	  template <class T>

	  concept bool View = Range<T> && Semiregular<T>  (ranges TS)

	  && /*	view-predicate<T> */;
	  template<class T>				  (ranges TS)
	  struct enable_view {};
	  struct view_base {};				  (ranges TS)

	  The  concept View<T> specifies the semiregular range T has constant-
       time copy, move,
	  and assignment operations.

	  The /* view-predicate<T> */ portion of the concept is	determined  as
       follows:

	    *  if  the	qualified-id ranges::enable_view<T>::type is valid and
       denotes a type,
	      ranges::enable_view<T>::type::value;
	    * otherwise, if std::is_base_of_v<ranges::view_base, T>  is	 true,
       true;
	    *  otherwise,  if  T is a specialization of	std::initializer_list,
       std::set,
	      std::multiset, std::unordered_set,  or  std::unordered_multiset,
       false;
	    *  otherwise, if both T and	const T	satisfy	Range and ranges::ref-
       erence_t
	      <ranges::iterator_t<T>> is not the same type as
	      ranges::reference_t<ranges::iterator_t<const T>>,	false;
	    * otherwise, true.
