Enum Timestamp

pub enum Timestamp {
    Specified(i64),
    UnspecifiedContinuous(UnspecifiedContinuous),
    UnspecifiedBestEffort(UnspecifiedBestEffort),
    // some variants omitted
}

Indicates the position of an audio packet in the stream timeline.

Variants

Specified(i64)

Specific time in the stream timeline. Units vary and are provided when the connection is established.

UnspecifiedContinuous(UnspecifiedContinuous)

Indicates the packet should be presented immediately after the previous packet, if there is a previous packet. If there is no previous packet, this option is equivalent to a specified value of 0.

This option implies that the stream timeline should not ‘slip’ even if the packet arrives late. The packet is intended to be presented immediately after the previous packet, and the resulting timing is to be maintained regardless of the arrival time of the packet.

UnspecifiedBestEffort(UnspecifiedBestEffort)

Indicates the packet should be presented as soon as possible after the previous packet, if there is one, as soon as possible if not.

This option implies that the stream time should ‘slip’ if the packet arrives too late to be rendered immediately after the previous packet. This option is often used when a gap occurs in an un-timestamped stream, perhaps due to a lossy upstream source.

Implementations

impl Timestamp

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> Self

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Timestamp

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

Formats the value using the given formatter.

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

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<D: ResourceDialect> Encode<Timestamp, D> for &Timestamp

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 Timestamp

fn eq(&self, other: &Self) -> 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 Timestamp

type Owned = Timestamp

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 Timestamp

type Borrowed<'a> = &'a Timestamp

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.
