1) Returns static_cast<std::iter_const_reference_t<Iter>>(*base()).
2) If Iter models
, 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.
