An InputDevice driver represents a single physical input device. The InputDevice maintains an internal FIFO of MAX_DEVICE_REPORT_COUNT reports for each client that connects. Reports are removed from the FIFO once they are read by the client. If the FIFO is full, it will drop the oldest report to make room for an incoming report.

Variants

GetInputReportsReader

Open a new InputReportsReader on this device. Each reader receives their own reports.

Fields

reader: ServerEnd<InputReportsReaderMarker>

control_handle: InputDeviceControlHandle

GetDescriptor

Gets the device descriptor for this device.

Fields

responder: InputDeviceGetDescriptorResponder

SendOutputReport

Send a single output report to the device. This will throw an error if the output report does not follow the OutputDescriptor.

Fields

report: OutputReport

responder: InputDeviceSendOutputReportResponder

GetFeatureReport

Get the feature report for a given device. This requests the state of the device’s features.

Fields

responder: InputDeviceGetFeatureReportResponder

SetFeatureReport

Set the feature report for a given device. This sets the state of the device’s features.

Fields

report: FeatureReport

responder: InputDeviceSetFeatureReportResponder

GetInputReport

For general cases, InputReportReader is the preferred way of getting InputReports. For devices that don’t send InputReports naturally, this method can be used to request a report from the device type indicated. Does not block, and returns ZX_ERR_NOT_SUPPORTED if GetInputReport or device_type are not supported.

Fields

device_type: DeviceType

responder: InputDeviceGetInputReportResponder

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: InputDeviceControlHandle

method_type: MethodType
