::swap
void swap (packaged_task& x) noexcept;
Swap packaged_task
Exchanges the
shared state
and
stored task
with
x
.
Parameters
x
Another
packaged_task
object of the same type (with the same template parameters,
Ret
and
Args...
).
Return value
none
Data races
Both
x
and the object are modified.
Exception safety
No-throw guarantee:
never throws exceptions.
