Fields

sample_entry: SampleEntry

The sample entry that this entry inherits from.

reserved1: u64

Reserved 64 bits, must be set to 0.

channelcount: u16

The number of channels.

• 0: inapplicable/unknown
• 1: mono
• 2: stereo (left/right)
• all other values: the codec configuration should identify the channel assignment.

samplesize: u16

In bits, and takes the default value of 16.

pre_defined: u16

Pre-defined 16 bit value, must be set to 0.

reserved2: u16

Reserved 16 bits, must be set to 0.

samplerate: FixedU32<U16>

When a SamplingRateBox is absent is the sampling rate; when a SamplingRateBox is present, is a suitable integer multiple or division of the actual sampling rate.

Implementations

impl AudioSampleEntry

pub fn new( sample_entry: SampleEntry, channelcount: u16, samplesize: u16, samplerate: FixedU32<U16>, ) -> Self

Creates a new AudioSampleEntry with the given parameters.

Trait Implementations

impl Debug for AudioSampleEntry

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for AudioSampleEntry

fn deserialize<R>(reader: R) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl IsoSized for AudioSampleEntry

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for AudioSampleEntry

fn eq(&self, other: &AudioSampleEntry) -> 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 Serialize for AudioSampleEntry

fn serialize<W>(&self, writer: W) -> Result<()>

where W: Write,

Serialize the value into the given writer.

impl Eq for AudioSampleEntry

impl StructuralPartialEq for AudioSampleEntry
