source§fn init(&mut self) -> Result<()>
fn init(&mut self) -> Result<()>
Perform any necessary initialization before receiving and sending events from/to the source.
source§fn finalize(&mut self) -> Result<()>
fn finalize(&mut self) -> Result<()>
Perform any necessary cleanup when the device will no longer be used.
source§fn receive_events(&mut self) -> Result<usize>
fn receive_events(&mut self) -> Result<usize>
Receive events from the source, filters them and stores them in a queue for future
consumption by reading from this object. Returns the number of new non filtered events
received. This function may block waiting for events to be available.
source§fn available_events_count(&self) -> usize
fn available_events_count(&self) -> usize
Returns the number of received events that have not been filtered or consumed yet.
source§fn pop_available_event(&mut self) -> Option<virtio_input_event>
fn pop_available_event(&mut self) -> Option<virtio_input_event>
Returns the next available event
source§fn send_event(&mut self, vio_evt: &virtio_input_event) -> Result<()>
fn send_event(&mut self, vio_evt: &virtio_input_event) -> Result<()>
Sends a status update event to the source

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