Struct DeviceInfo

pub struct DeviceInfo {
    pub min_descriptor_length: Option<u8>,
    pub descriptor_version: Option<u8>,
    pub base_info: Option<DeviceBaseInfo>,
    /* private fields */
}

Network device information.

Fields

min_descriptor_length: Option<u8>

Minimum descriptor length, in 64-bit words. Required.

The minimum length that each buffer descriptor must have for correct operation with this device. Devices that support extra frame metadata inform larger minimum descriptor lengths that reflect the minimum space needed to be able to store frame metadata.

descriptor_version: Option<u8>

Accepted descriptor version. Required.

base_info: Option<DeviceBaseInfo>

Device base info. Required.

Trait Implementations

impl Clone for DeviceInfo

fn clone(&self) -> DeviceInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceInfo

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

Formats the value using the given formatter.

impl<D> Decode<DeviceInfo, D> for DeviceInfo

where D: ResourceDialect,

fn new_empty() -> DeviceInfo

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<(), Error>

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

impl Default for DeviceInfo

fn default() -> DeviceInfo

Returns the “default value” for a type.

impl<D> Encode<DeviceInfo, D> for &DeviceInfo

where D: ResourceDialect,

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

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

impl PartialEq for DeviceInfo

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

type Owned = DeviceInfo

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 DeviceInfo

type Borrowed<'a> = &'a DeviceInfo

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: &<DeviceInfo as TypeMarker>::Owned, ) -> <DeviceInfo as ValueTypeMarker>::Borrowed<'_>

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