Struct CompositeProperties

pub struct CompositeProperties {
    pub manufacturer: Option<String>,
    pub product: Option<String>,
    pub unique_id: Option<[u8; 16]>,
    pub clock_domain: Option<u32>,
    /* private fields */
}

Fields

manufacturer: Option<String>

UI string for the manufacturer name. If not set, the manufacturer is unknown. If included, this string must be non-empty.

Optional.

product: Option<String>

UI string for the product name. If not set, the product name is unknown. If included, this string must be non-empty.

Optional.

unique_id: Option<[u8; 16]>

A unique identifier. If not included, there is no unique id for the Device. unique_id arrays starting with 0x42, 0x54, … (or BT in ASCII) are reserved for drivers implementing Bluetooth technologies. unique_id arrays starting with 0x55, 0x53, 0x42, … (or USB in ASCII) are reserved for drivers implementing USB technologies. Note that even though the above values map to readable ASCII characters, array values can span the entire uint8 range (0-255).

Optional.

clock_domain: Option<u32>

An identifier for the clock domain in which this hardware operates. If two hardware devices have the same clock domain, their clock rates are identical and perfectly synchronized. Although these two clocks have the same rate, the clock positions may be offset from each other by an arbitrary (but fixed) amount. The clock_domain typically comes from a system wide entity, such as a platform bus or global clock tree.

There are two special values:

• CLOCK_DOMAIN_MONOTONIC means the hardware is operating at the same rate as the system montonic clock.

• CLOCK_DOMAIN_EXTERNAL means the hardware is operating at an unknown rate and is not synchronized with any known clock, not even with other clocks in domain CLOCK_DOMAIN_EXTERNAL.

If the domain is not CLOCK_DOMAIN_MONOTONIC, client must use position notification updates to recover the hardware’s clock.

Required.

Trait Implementations

impl Clone for CompositeProperties

fn clone(&self) -> CompositeProperties

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompositeProperties

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

Formats the value using the given formatter.

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

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 CompositeProperties

fn default() -> CompositeProperties

Returns the “default value” for a type.

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

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 CompositeProperties

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

type Owned = CompositeProperties

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 CompositeProperties

type Borrowed<'a> = &'a CompositeProperties

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.
