Constructs a new stop_source object.
1) Constructs a
stop_source with new stop-state.2) Constructs an empty
stop_source with no associated stop-state.3) Copy constructor. Constructs a
stop_source whose associated stop-state is the same as that of other.
4) Move constructor. Constructs a
stop_source whose associated stop-state is the same as that of other; other
Parameters
| nss | - | an std::nostopstate_t placeholder object to construct an empty stop_source
|
| other | - | another stop_source object to construct this stop_source object with

Postconditions
1)
stop_possible() is true and stop_requested() is false
2)
stop_possible() and stop_requested() are both false
3)
*this and other
4)
*this has other's previously associated stop-state, and other.stop_possible() is false
Exceptions
1) std::bad_alloc if memory could not be allocated for the stop-state.
