constexpr std::iter_const_reference_t<Iter> operator*() const;	(1)	(C++23 起)
constexpr const auto* operator->() const     requires std::is_lvalue_reference_v<std::iter_reference_t<Iterator>> &&         std::same_as<std::remove_cvref_t<std::iter_reference_t<Iterator>>,                      value_type>;	(2)	(C++23 起)

返回當前元素的 const 版本的引用或指標。

1) 返回 static_cast<std::iter_const_reference_t<Iter>>(*base())。

2) 如果 Iter 滿足 contiguous_iterator，返回 std::to_address(base())；否則，返回 std::addressof(*base())。

引數

(無)

返回值

1) 指向當前元素的 const 引用。結果可以是一個純右值（例如，如果 *base() 是一個純右值）。

2) 指向當前元素的 const 指標。
