Struct DriverInfo

pub struct DriverInfo {
    pub url: Option<String>,
    pub name: Option<String>,
    pub colocate: Option<bool>,
    pub package_type: Option<DriverPackageType>,
    pub is_fallback: Option<bool>,

    pub is_disabled: Option<bool>,
    /* private fields */
}

General information for a driver, used with both composite and normal drivers.

Fields

url: Option<String>

URL of the driver component.

name: Option<String>

Name of the driver, taken from the first field of the ZIRCON_DRIVER macro in the driver.

colocate: Option<bool>

If this is true then the driver should be colocated in its parent’s DriverHost.

package_type: Option<DriverPackageType>

The type of package this driver is in.

is_fallback: Option<bool>

If this is true then the driver is a fallback driver. Fallback drivers have a lesser priority for binding, so they will only be chosen for binding if there is no non-fallback driver that has matched.

device_categories: Option<Vec<DeviceCategory>>

Device categories

bind_rules_bytecode: Option<Vec<u8>>

Bind rules which declare set of constraints to evaluate in order to determine whether the driver indexer should bind this driver to a device.

driver_framework_version: Option<u8>

The version of the driver framework that this driver is using. Supported values are 1 (DFv1) and 2 (DFv2). If not provided, 1 is the assumed version.

is_disabled: Option<bool>

Whether the driver is disabled. If true, this driver is not chosen to bind to nodes.

Trait Implementations

impl Clone for DriverInfo

fn clone(&self) -> DriverInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DriverInfo

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

Formats the value using the given formatter.

impl<D> Decode<DriverInfo, D> for DriverInfo

where D: ResourceDialect,

fn new_empty() -> DriverInfo

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 DriverInfo

fn default() -> DriverInfo

Returns the “default value” for a type.

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

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 DriverInfo

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

type Owned = DriverInfo

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 DriverInfo

type Borrowed<'a> = &'a DriverInfo

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

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