Struct InputDevice

pub struct InputDevice {
    pub device_name: Option<String>,
    pub device_type: Option<DeviceType>,
    pub source_states: Option<Vec<SourceState>>,
    pub mutable_toggle_state: Option<ToggleStateFlags>,
    pub state: Option<DeviceState>,
    /* private fields */
}

Contains the information for an input device. The device is uniquely identified by the combination of device_name and device_type.

Fields

device_name: Option<String>

Uniquely identifies a device within a device type.

device_type: Option<DeviceType>

The type of input device (e.g. camera, microphone).

source_states: Option<Vec<SourceState>>

The state for each individual DeviceStateSource.

mutable_toggle_state: Option<ToggleStateFlags>

The software toggle states which are allowed to be changed for a device.

state: Option<DeviceState>

The overall state of the device, considering the combination of the source states.

Trait Implementations

impl Clone for InputDevice

fn clone(&self) -> InputDevice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InputDevice

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

Formats the value using the given formatter.

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

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 InputDevice

fn default() -> InputDevice

Returns the “default value” for a type.

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

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 InputDevice

fn eq(&self, other: &InputDevice) -> 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 InputDevice

type Owned = InputDevice

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 InputDevice

type Borrowed<'a> = &'a InputDevice

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.
