Struct AudioFilePacketTableInfo

#[repr(C)]
pub struct AudioFilePacketTableInfo {
    pub mNumberValidFrames: i64,
    pub mPrimingFrames: i32,
    pub mRemainderFrames: i32,
}

Available on crate feature AudioFile only.

This contains information about the number of valid frames in a file and where they begin and end.

Some data formats may have packets whose contents are not completely valid, but represent priming or remainder frames that are not meant to be played. For example a file with 100 packets of AAC is nominally 1024 * 100 = 102400 frames of data. However the first 2112 frames of that may be priming frames and there may be some number of remainder frames added to pad out to a full packet of 1024 frames. The priming and remainder frames should be discarded. The total number of packets in the file times the frames per packet (or counting each packet’s frames individually for a variable frames per packet format) minus mPrimingFrames, minus mRemainderFrames, should equal mNumberValidFrames.

Trait Implementations

impl Clone for AudioFilePacketTableInfo

fn clone(&self) -> AudioFilePacketTableInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioFilePacketTableInfo

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

Formats the value using the given formatter.

impl Encode for AudioFilePacketTableInfo

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for AudioFilePacketTableInfo

fn eq(&self, other: &AudioFilePacketTableInfo) -> 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.
