1) Constructs an
observer_ptr that has no corresponding watched object.2) Constructs an
observer_ptr that watches p.
3) Constructs an
observer_ptr that watches other.get(). This overload participates in overload resolution only if W2* is convertible to element_type*
4,5) Implicitly declared copy and move constructors. Constructs an
observer_ptr that watches other.get()
Parameters
| p | - | a pointer to an object to watch |
| other | - | another observer_ptr to copy from
