Struct DeviceDescriptor 

pub struct DeviceDescriptor {
    pub mouse: Option<MouseDescriptor>,
    pub sensor: Option<SensorDescriptor>,
    pub touch: Option<TouchDescriptor>,
    pub keyboard: Option<KeyboardDescriptor>,
    pub consumer_control: Option<ConsumerControlDescriptor>,
    pub device_information: Option<DeviceInformation>,
    /* private fields */
}

DeviceDescriptor describes a physical input device. Some physical devices may send multiple types of reports (E.g: a physical touchscreen can send touch and stylus reports, so it will have both a TouchDescriptor and a StylusDescriptor).

Fields

mouse: Option<MouseDescriptor>

Describes the mouse part of the device.

Optional. Present iff the device is/has a mouse.

sensor: Option<SensorDescriptor>

Describes the sensor part of the device.

Optional. Present iff the device is/has a sensor.

touch: Option<TouchDescriptor>

Describes the touch part (such as a touchscreen or touchpad) of the device.

Optional. Present iff the device is/has a touch device.

keyboard: Option<KeyboardDescriptor>

Describes the keyboard part of the device.

Optional. Present iff the device is/has a keyboard.

consumer_control: Option<ConsumerControlDescriptor>

Describes the consumer control part of the device.

Optional. Present iff the device is/has a consumer control device.

device_information: Option<DeviceInformation>

Identifies the physical device.

Required.

Trait Implementations

impl Clone for DeviceDescriptor

fn clone(&self) -> DeviceDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceDescriptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<DeviceDescriptor, D> for DeviceDescriptor

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for DeviceDescriptor

fn default() -> DeviceDescriptor

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<DeviceDescriptor, D> for &DeviceDescriptor

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for DeviceDescriptor

fn eq(&self, other: &DeviceDescriptor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeMarker for DeviceDescriptor

type Owned = DeviceDescriptor

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for DeviceDescriptor

type Borrowed<'a> = &'a DeviceDescriptor

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
