NAME¶
std::experimental::ranges::reference_t,std::experimental::ranges::rvalue_reference_t, - std::experimental::ranges::reference_t,std::experimental::ranges::rvalue_reference_t,
Synopsis¶
Defined in header <experimental/ranges/iterator>
template< class T > (exposition
concept bool /*dereferenceable*/ = requires(T& t) { {*t} ->
auto&&; only*)
};
template< /*dereferenceable*/ T > (1) (ranges TS)
using reference_t = decltype(*declval<T&>());
template< /*dereferenceable*/ T >
requires requires(T& t) { { ranges::iter_move(t) } -> auto&&;
} (2) (ranges TS)
using rvalue_reference_t =
decltype(ranges::iter_move(declval<T&>()));
template< Readable T >
using iter_common_reference_t =
ranges::common_reference_t<ranges::reference_t<T>, (3)
(ranges TS)
ranges::value_type_t<T>&>;
1) Obtain the reference type of a dereferenceable type T.
2) Obtain the rvalue reference type of a dereferenceable type T, that is, the
return
type of ranges::iter_move.
3) Compute a Readable type's common reference type. This is the common
reference
type of its reference type and an lvalue reference to its value type.
Notes¶
The -> auto&& constraint checks that the type of the expression is not void.
