Struct DeviceEvent 

pub struct DeviceEvent {
    pub action: Option<Action>,
    pub device_id: Option<u32>,
    pub descriptor: Option<DeviceDescriptor>,
    /* private fields */
}

Represents an event associated with a change in the input devices.

Fields

action: Option<Action>

The action that triggered this event.

device_id: Option<u32>

The unique identifier of the device.

descriptor: Option<DeviceDescriptor>

The descriptor containing detailed information about the device.

Trait Implementations

impl Clone for DeviceEvent

fn clone(&self) -> DeviceEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceEvent

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

Formats the value using the given formatter.

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

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 DeviceEvent

fn default() -> DeviceEvent

Returns the “default value” for a type.

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

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 DeviceEvent

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

Equality operator ==.

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

Inequality operator !=.

impl Persistable for DeviceEvent

impl StructuralPartialEq for DeviceEvent

impl TypeMarker for DeviceEvent

type Owned = DeviceEvent

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 DeviceEvent

type Borrowed<'a> = &'a DeviceEvent

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.
