Implementations§

source§

impl EventDevice

source

pub fn new(kind: EventDeviceKind, event_socket: StreamChannel) -> EventDevice

source

pub fn mouse(event_socket: StreamChannel) -> EventDevice

source

pub fn touchscreen(event_socket: StreamChannel) -> EventDevice

source

pub fn keyboard(event_socket: StreamChannel) -> EventDevice

source

pub fn kind(&self) -> EventDeviceKind

source

pub fn flush_buffered_events(&mut self) -> Result<bool>

Flushes the buffered events that did not fit into the underlying transport, if any.

Returns Ok(true) if, after this function returns, there all the buffer of events is empty.

source

pub fn is_buffered_events_empty(&self) -> bool

source

fn can_buffer_events(&self, num_events: usize) -> bool

Determines if there is space in the event buffer for the given number of events. The buffer is capped at EVENT_BUFFER_LEN_MAX.

source

pub fn send_report<E: IntoIterator<Item = virtio_input_event>>( &mut self, events: E ) -> Result<bool>

source

pub fn send_event_encoded(&mut self, event: virtio_input_event) -> Result<bool>

Sends the given event, returning Ok(true) if, after this function returns, there are no buffered events remaining.

source

pub fn recv_event_encoded(&self) -> Result<virtio_input_event>
