Struct DeviceInformation

pub struct DeviceInformation {
    pub vendor_id: Option<u32>,
    pub product_id: Option<u32>,
    pub version: Option<u32>,
    pub polling_rate: Option<i64>,
    /* private fields */
}

DeviceInformation provides more information about the device and lets a client distinguish between devices (e.g between two touchscreens that come from different vendors). If the device is a HID device, then the id information will come from the device itself. Other, non-HID devices may assign the ids in the driver, so it will be the driver author’s responsibility to assign sensible ids.

Fields

vendor_id: Option<u32>

product_id: Option<u32>

version: Option<u32>

polling_rate: Option<i64>

Trait Implementations

impl Clone for DeviceInformation

fn clone(&self) -> DeviceInformation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceInformation

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

Formats the value using the given formatter.

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

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 DeviceInformation

fn default() -> DeviceInformation

Returns the “default value” for a type.

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

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 DeviceInformation

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

type Owned = DeviceInformation

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 DeviceInformation

type Borrowed<'a> = &'a DeviceInformation

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.
