std::basic_const_iterator
constexpr std::iter_const_reference_t <Iter> operator* ( ) const ;
(1) (since C++23)
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) (since C++23)

Returns a reference or pointer to the const version of the current element.

1) Returns static_cast < std::iter_const_reference_t <Iter>> ( *base( ) )
2) If Iter models contiguous_iterator, returns std::to_address (base( ) ) ; otherwise, returns std::addressof ( *base( ) )

Parameters

(none)

Return value

1) Reference-to-const that refers to the current element. The result may be a prvalue (e.g. if *base() is a prvalue).
2) Pointer-to-const that points to the current element.
