NAME
std::ranges::views::as_rvalue,std::ranges::as_rvalue_view - std::ranges::views::as_rvalue,std::ranges::as_rvalue_view

Synopsis
   Defined in header <ranges>
   template< ranges::view V >
       requires ranges::input_range<V> (1) (since C++23)
   class as_rvalue_view
       : public ranges::view_interface<as_rvalue_view<V>>
   namespace views {
       inline constexpr /* unspecified */ as_rvalue = /* unspecified (2) (since C++23)
   */;
   }
   Call signature
   template< ranges::viewable_range R >
       requires /* see below */ (since C++23)
   constexpr ranges::view auto as_rvalue( R&& r );
   1) A range adaptor that represents a view of underlying view whose elements are
   rvalues.
   2) RangeAdaptorObject. Let e be a subexpression and let T be decltype((e)). Then the
   expression views::as_rvalue(e) is expression-equivalent to:
     * views::all(e), if it is a well-formed expression and
       std::same_as<ranges::range_rvalue_reference_t<T>, ranges::range_reference_t<T>>
       is true;
     * as_rvalue_view{e} otherwise.

Member functions
   constructor constructs an as_rvalue_view
                 (public member function)
   base returns the underlying view V
                 (public member function)
   begin returns the beginning iterator of the as_rvalue_view
                 (public member function)
   end returns the end iterator of the as_rvalue_view
                 (public member function)
   size returns the size of the view if it is bounded
                 (public member function)
         Inherited from std::ranges::view_interface
   empty returns whether the derived view is empty. Provided if it satisfies
   (C++20) sized_range or forward_range.
                 (public member function of std::ranges::view_interface<D>)
   cbegin returns a constant iterator to the beginning of the range.
   (C++23) (public member function of std::ranges::view_interface<D>)
   cend returns a sentinel for the constant iterator of the range.
   (C++23) (public member function of std::ranges::view_interface<D>)
   operator bool returns whether the derived view is not empty. Provided if
   (C++20) ranges::empty is applicable to it.
                 (public member function of std::ranges::view_interface<D>)
   front returns the first element in the derived view. Provided if it
   (C++20) satisfies forward_range.
                 (public member function of std::ranges::view_interface<D>)
   back returns the last element in the derived view. Provided if it satisfies
   (C++20) bidirectional_range and common_range.
                 (public member function of std::ranges::view_interface<D>)
   operator[] returns the n^th element in the derived view. Provided if it satisfies
   (C++20) random_access_range.
                 (public member function of std::ranges::view_interface<D>) std::ranges::as_rvalue_view::as_rvalue_view
   as_rvalue_view() requires std::default_initializable<V> = default; (1) (since C++23)
   constexpr explicit as_rvalue_view( V base ); (2) (since C++23)
   1) Value-initializes base_ via its default member initializer (= V()).
   2) Initializes base_ with std::move(base).

Parameters
   base - a view std::ranges::as_rvalue_view::base
   constexpr V base() const& requires std::copy_constructible<V>; (1) (since C++23)
   constexpr V base() &&; (2) (since C++23)
   Returns the underlying view.
   1) Copy-constructs the result from the underlying view. Equivalent to return base_;.
   2) Move-constructs the result from the underlying view. Equivalent to return
   std::move(base_);. std::ranges::as_rvalue_view::begin
   constexpr auto begin() requires (!__simple_view<V>); (1) (since C++23)
   constexpr auto begin() const requires ranges::range<const V>; (2) (since C++23)
   1,2) Returns std::move_iterator(ranges::begin(base_)). std::ranges::as_rvalue_view::end
   constexpr auto end() requires (!__simple_view<V>); (1) (since C++23)
   constexpr auto end() const requires ranges::range<const V>; (2) (since C++23)
   1) Returns std::move_iterator(ranges::end(base_)) if V models common_range,
   otherwise std::move_sentinel(ranges::end(base_)).
   2) Returns std::move_iterator(ranges::end(base_)) if const V models common_range,
   otherwise std::move_sentinel(ranges::end(base_)). std::ranges::as_rvalue_view::size
   constexpr auto size() requires ranges::sized_range<V>; (1) (since C++23)
   constexpr auto size() const requires ranges::sized_range<const V>; (2) (since C++23)
   Returns the size of the view if the view is bounded.
   1,2) Equivalent to return ranges::size(base_);
   Deduction guides
   template< class R > (since C++23)
   as_rvalue_view( R&& ) -> as_rvalue_view<views::all_t<R>>;
   Helper templates
   template< class T >
   inline constexpr bool enable_borrowed_range<std::ranges::as_rvalue_view<T>> (since
   = C++23)
       std::ranges::enable_borrowed_range<T>;
   This specialization of std::ranges::enable_borrowed_range makes as_rvalue_view
   satisfy borrowed_range when the underlying view satisfies it.
