Struct VirtIOInput

pub struct VirtIOInput<H: Hal, T: Transport> { /* private fields */ }

Virtual human interface devices such as keyboards, mice and tablets.

An instance of the virtio device represents one such input device. Device behavior mirrors that of the evdev layer in Linux, making pass-through implementations on top of evdev easy.

Implementations

impl<H: Hal, T: Transport> VirtIOInput<H, T>

pub fn new(transport: T) -> Result<Self, Error>

Create a new VirtIO-Input driver.

pub fn ack_interrupt(&mut self) -> bool

Acknowledge interrupt and process events.

pub fn pop_pending_event(&mut self) -> Option<InputEvent>

Pop the pending event.

pub fn query_config_select( &mut self, select: InputConfigSelect, subsel: u8, out: &mut [u8], ) -> u8

Query a specific piece of information by select and subsel, and write result to out, return the result size.

pub fn name(&mut self) -> Result<String, Error>

Queries and returns the name of the device, or an error if it is not valid UTF-8.

pub fn serial_number(&mut self) -> Result<String, Error>

Queries and returns the serial number of the device, or an error if it is not valid UTF-8.

pub fn ids(&mut self) -> Result<DevIDs, Error>

Queries and returns the ID information of the device.

pub fn prop_bits(&mut self) -> Result<Box<[u8]>, Error>

Queries and returns the input properties of the device.

pub fn ev_bits(&mut self, event_type: u8) -> Result<Box<[u8]>, Error>

Queries and returns a bitmap of supported event codes for the given event type.

If the event type is not supported an empty slice will be returned.

pub fn abs_info(&mut self, axis: u8) -> Result<AbsInfo, Error>

Queries and returns information about the given axis of the device.
