TouchBinding

input_pipeline::touch_binding

Struct TouchBinding 

Source 
pub struct TouchBinding { /* private fields */ }
Expand description

A TouchBinding represents a connection to a touch input device.

The TouchBinding parses and exposes touch descriptor properties (e.g., the range of possible x values for touch contacts) for the device it is associated with. It also parses InputReports from the device, and sends them to the device binding owner over event_sender.

Implementations§

Source§

impl TouchBinding

Source

pub async fn new( device_proxy: InputDeviceProxy, device_id: u32, input_event_sender: UnboundedSender<InputEvent>, device_node: Node, metrics_logger: MetricsLogger, ) -> Result<Self, Error>

Creates a new InputDeviceBinding from the device_proxy.

The binding will start listening for input reports immediately and send new InputEvents to the device binding owner over input_event_sender.

§Parameters
  • device_proxy: The proxy to bind the new InputDeviceBinding to.
  • device_id: The id of the connected touch device.
  • input_event_sender: The channel to send new InputEvents to.
  • device_node: The inspect node for this device binding
  • metrics_logger: The metrics logger.
§Errors

If there was an error binding to the proxy.
