Public Types
using difference_type = typename __difference< _Ptr >::type
The type used to represent the difference between two pointers.
using element_type = _Elt

using pointer = _Ptr
The pointer type.
template<typename _Up > using rebind = typename __rebind< _Ptr, _Up >::type
A pointer to a different type.
Static Public Member Functions
