std::experimental::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> && /* view-predicate<T> (ranges TS)
   */;
   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::reference_t
       <ranges::iterator_t<T>> is not the same type as
       ranges::reference_t<ranges::iterator_t<const T>>, false;
     * otherwise, true.
