           The type used to represent the difference between two pointers.
       using element_type = _Elt
           The type pointed to.
       using pointer = _Ptr
           The pointer type.
       template<typename _Up > using rebind = typename __detected_or_t< __replace_first_arg<
           _Ptr, _Up >, __rebind, _Ptr, _Up >::type

   template<typename _Ptr , typename _Elt > using std::__ptr_traits_impl< _Ptr, _Elt
       >::difference_type =  __detected_or_t<ptrdiff_t, __diff_t, _Ptr> [inherited]
       The type used to represent the difference between two pointers.

   template<typename _Ptr , typename _Elt > using std::__ptr_traits_impl< _Ptr, _Elt
       >::element_type =  _Elt [inherited]
       The type pointed to.

   template<typename _Ptr , typename _Elt > using std::__ptr_traits_impl< _Ptr, _Elt >::pointer =
       _Ptr [inherited]
       The pointer type.

   template<typename _Ptr , typename _Elt > template<typename _Up > using std::__ptr_traits_impl<
       _Ptr, _Elt >::rebind =  typename __detected_or_t<__replace_first_arg<_Ptr, _Up>, __rebind,

       A pointer to a different type.

Member Function Documentation

   template<typename _Ptr , typename _Elt , bool  = is_void<_Elt>::value> static pointer
       std::__ptr_traits_ptr_to< _Ptr, _Elt, bool >::pointer_to (element_type & __r) [inline],
       [static],  [inherited]
       Obtain a pointer to an object.

       Parameters
           __r A reference to an object of type element_type

       Returns
           pointer::pointer_to(__r)

       Precondition
           pointer::pointer_to(__r) is a valid expression.
