Enum fidl_fuchsia_device_manager::DeviceType

pub enum DeviceType {
    Stub(StubDevice),
    Proxy(ProxyDevice),
    FidlProxy(FidlProxyDevice),
    Composite(CompositeDevice),
}

Variants

Stub(StubDevice)

The device has no parent to communicate with and no driver to load.

Proxy(ProxyDevice)

The device acts as a proxy for its parent and talks to it via its proxy channel.

FidlProxy(FidlProxyDevice)

This device is a proxy for its parent which lives in another driver host. The parent exposes FIDL protocols in its outgoing directory, which have been routed to this device.

Composite(CompositeDevice)

The device is a composite device with several parents, referred to as fragments. The device aggregates all parent devices together. The order of the fragments will match the original composite creation request.

Implementations

impl DeviceType

pub fn ordinal(&self) -> u64

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict unions should not use is_unknown

Trait Implementations

impl Debug for DeviceType

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

Formats the value using the given formatter.

impl Decode<DeviceType> for DeviceType

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<'_>, offset: usize, depth: Depth ) -> Result<()>

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

impl Encode<DeviceType> for &mut DeviceType

unsafe fn encode( self, encoder: &mut Encoder<'_>, 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 Hash for DeviceType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DeviceType

fn cmp(&self, other: &DeviceType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<DeviceType> for DeviceType

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<DeviceType> for DeviceType

fn partial_cmp(&self, other: &DeviceType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl ResourceTypeMarker for DeviceType

type Borrowed<'a> = &'a mut DeviceType

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &mut Self::Owned. There are three cases:

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for DeviceType

type Owned = DeviceType

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.
