Struct CMSampleTimingInfo 

#[repr(C)]
pub struct CMSampleTimingInfo {
    pub duration: CMTime,
    pub presentationTimeStamp: CMTime,
    pub decodeTimeStamp: CMTime,
}

Available on crate features CMSampleBuffer and CMTime only.

Collection of timing info for a sample in a CMSampleBuffer. A single CMSampleTimingInfo struct can describe every individual sample in a CMSampleBuffer, if the samples all have the same duration and are in presentation order with no gaps.

See also Apple’s documentation

Fields

duration: CMTime

The duration of the sample. If a single struct applies to each of the samples, they all will have this duration.

presentationTimeStamp: CMTime

The time at which the sample will be presented. If a single struct applies to each of the samples, this is the presentationTime of the first sample. The presentationTime of subsequent samples will be derived by repeatedly adding the sample duration.

decodeTimeStamp: CMTime

The time at which the sample will be decoded. If the samples are in presentation order (eg. audio samples, or video samples from a codec that doesn’t support out-of-order samples), this can be set to kCMTimeInvalid.

Trait Implementations

impl Clone for CMSampleTimingInfo

fn clone(&self) -> CMSampleTimingInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CMSampleTimingInfo

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

Formats the value using the given formatter.

impl Encode for CMSampleTimingInfo

Available on crate feature objc2 only.

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for CMSampleTimingInfo

fn eq(&self, other: &CMSampleTimingInfo) -> 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 RefEncode for CMSampleTimingInfo

Available on crate feature objc2 only.

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Copy for CMSampleTimingInfo
