Destroys a jss::update_guard<>
instance and unlocks the mutex on the associated jss::synchronized_value<>
object.
~update_guard();
Unlocks the internal mutex in the jss::synchronized_value<>
instance sv supplied
when *this
was constructed.
Nothing.
The destruction of an jss::update_guard<>
instance synchronizes-with the construction
of a subsequent jss::update_guard<>
instance referencing the same jss::synchronized_value<>
instance, or a subsequent use of the pointer dereference operator
or member access operator on that jss::synchronized_value<>
instance.
