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 is left empty.
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 share the same associated stop-state and compare equal
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
