NAME
std::pointer_traits::to_address - std::pointer_traits::to_address

Synopsis
   Defined in header <memory>
   static element_type* to_address( pointer p ) (since C++20)
   noexcept; (optional member of program-defined
                        specialization)
   Constructs a raw pointer that references the same object as its pointer-like ("fancy

   customization point to be called by std::to_address.

Parameters
   p - fancy pointer/pointer-like object

Return value
   A raw pointer of the type element_type* that references the same memory location as
   the argument p.
