Struct PacketStream 

pub struct PacketStream {
    pub supported_buffer_types: Option<BufferType>,
    pub needs_cache_flush_or_invalidate: Option<bool>,
    /* private fields */
}

Configuration for a fuchsia.hardware.audio/PacketStreamControl.

Fields

supported_buffer_types: Option<BufferType>

The buffer methods supported by this driver.

Required.

needs_cache_flush_or_invalidate: Option<bool>

When set to true, indicates that the packet-stream runs in a different cache coherency domain. Clients must ensure data writes are flushed to main memory (during output) or invalidated before reading (during input).

Optional.

Trait Implementations

impl Clone for PacketStream

fn clone(&self) -> PacketStream

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PacketStream

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

Formats the value using the given formatter.

impl<D> Decode<PacketStream, D> for PacketStream

where D: ResourceDialect,

fn new_empty() -> PacketStream

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 PacketStream

fn default() -> PacketStream

Returns the “default value” for a type.

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

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 PacketStream

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

type Owned = PacketStream

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 PacketStream

type Borrowed<'a> = &'a PacketStream

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

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