Class template for optional values and surrounding facilities, as described in n3793 "A proposal to add a utility class to represent optional objects (Revision 5)".
constexpr enable_if_t<!_Has_addressof<_Tp>::value, _Tp*> std::experimental::fundamentals_v1::__constexpr_addressof | ( | _Tp & | __t | ) |
An overload that attempts to take the address of an lvalue as a constant expression. Falls back to __addressof in the presence of an overloaded addressof operator (unary operator&), in which case the call will not be a constant expression.
Definition at line 177 of file optional.
