Represents a single device on a SPI bus.

Fields

cs: Option<u32>

Chip select number for the device.

vid: Option<u32>

Vendor ID. Used when binding via platform bus device IDs.

pid: Option<u32>

Product ID. Used when binding via platform bus device IDs.

did: Option<u32>

Device ID. Used when binding via platform bus device IDs.

cs_polarity_high: Option<bool>

Chip select polarity: true == high, false == low.

word_length_bits: Option<u8>

Size in bits of a single word on the SPI bus.

is_bus_controller: Option<bool>

Are we in charge of the bus?

clock_polarity_high: Option<bool>

Clock polarity. true == high, false == low.

clock_phase: Option<SpiClockPhase>

Clock phase.

max_frequency_hz: Option<u32>

Maximum bus frequency in Hz.

Trait Implementations

impl Clone for SpiChannel

fn clone(&self) -> SpiChannel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpiChannel

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

Formats the value using the given formatter.

impl<D> Decode<SpiChannel, D> for SpiChannel

where D: ResourceDialect,

fn new_empty() -> SpiChannel

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 SpiChannel

fn default() -> SpiChannel

Returns the “default value” for a type.

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

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 SpiChannel

fn eq(&self, other: &SpiChannel) -> 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 Persistable for SpiChannel

impl StructuralPartialEq for SpiChannel

impl TypeMarker for SpiChannel

type Owned = SpiChannel

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 SpiChannel

type Borrowed<'a> = &'a SpiChannel

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

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