where T: Read + Write + AsRawDescriptor,

pub fn new(source: T) -> EvdevEventSource<T>

Trait Implementations

impl<T: AsRawDescriptor> AsRawDescriptor for EvdevEventSource<T>

fn as_raw_descriptor(&self) -> RawDescriptor

Returns the underlying raw descriptor.

impl<T> EventSource for EvdevEventSource<T>

where T: Read + Write + AsRawDescriptor,

fn init(&mut self) -> Result<()>

Perform any necessary initialization before receiving and sending events from/to the source.

fn finalize(&mut self) -> Result<()>

Perform any necessary cleanup when the device will no longer be used.

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.

fn available_events_count(&self) -> usize

Returns the number of received events that have not been filtered or consumed yet.

fn pop_available_event(&mut self) -> Option<virtio_input_event>

Returns the next available event

fn send_event(&mut self, vio_evt: &virtio_input_event) -> Result<()>

Sends a status update event to the source
