Struct WeakSignalSubscription 

pub struct WeakSignalSubscription(/* private fields */);

A weak subscription to a D-Bus signal.

Like SignalSubscription but hold only a weak reference to the D-Bus connection the signal is subscribed on, i.e. maintain the subscription on the D-Bus signal only as long as some strong reference exists on the corresponding D-Bus connection.

When dropped, unsubscribes from signal on the connection if it still exists, and then drop the reference on the connection. If no other strong reference on the connection exists the connection is closed and destroyed.
