friend constexpr auto iter_move( const /*iterator*/& i )     noexcept(/* see description */);		(C++23 起)

返回对底层迭代器应用 ranges::iter_move 的结果。

等价于：return /*tuple-transform*/(ranges::iter_move, i.current_);，其中 current_ 是底层迭代器的数组。

此函数对于普通的非限定或限定查找不可见，只有当 adjacent_view::iterator<Const> 是参数的关联类时，才能通过实参依赖查找找到它。

参数

i

-

迭代器

返回值

对底层迭代器应用 ranges::iter_move 的结果。

异常

noexcept(

  noexcept(ranges::iter_move(declval<const ranges::iterator_t<Base>&>()))
  &&
  std::is_nothrow_move_constructible_v<ranges::range_rvalue_reference_t<Base>>
