Source§fn is_closed(&self) -> bool
fn is_closed(&self) -> bool
Returns if the subscription is closed or not. A subscription can be
closed by calling unsubscribe on it. Some special subscriptions made
by observables that only ever emit values during subscribe, will produce
subscriptions that are created closed. Read more
Source§fn unsubscribe(&mut self)
fn unsubscribe(&mut self)
Releases all resources associated with this subscription, and marks it
as closed. Read more

impl TeardownCollection for ErasedSubscription
Source§fn add_teardown(&mut self, teardown: Teardown)
fn add_teardown(&mut self, teardown: Teardown)
Add additional teardowns to execute on unsubscribe. If the subscription
is already closed, the added teardown is immediately executed!

fn into_any(self: Box<T>) -> Box<dyn Any>
Converts
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be
downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Converts
Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further
downcast into Rc<ConcreteType> where ConcreteType implements Trait.Source§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Converts
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.Source§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Converts
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot

Wrap this subscription into a SharedSubscription, erasing it and
allowing you to freely clone it, to unsubscribe it from multiple places.
