Struct retina::Timestamp

pub struct Timestamp { /* fields omitted */ }

A monotonically increasing timestamp within an RTP stream.

The Display and Debug implementations display:

• the bottom 32 bits, as seen in RTP packet headers. This advances at a codec-specified clock rate.
• the full timestamp, with top bits accumulated as RTP packet timestamps wrap around.
• a conversion to RTSP “normal play time” (NPT): zero-based and normalized to seconds.

Implementations

impl Timestamp

pub fn new(timestamp: i64, clock_rate: NonZeroU32, start: u32) -> Option<Self>

Creates a new timestamp unless timestamp - start underflows.

pub fn timestamp(&self) -> i64

Returns time since some arbitrary point before the stream started.

pub fn start(&self) -> u32

Returns timestamp of the start of the stream.

pub fn clock_rate(&self) -> NonZeroU32

Returns codec-specified clock rate, in Hz.

pub fn elapsed(&self) -> i64

Returns elapsed time since the stream start in clock rate units.

pub fn elapsed_secs(&self) -> f64

Returns elapsed time since the stream start in seconds, aka “normal play time” (NPT).

pub fn try_add(&self, delta: u32) -> Option<Self>

Returns self + delta unless it would overflow.

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 Display for Timestamp

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

Formats the value using the given formatter.

impl PartialEq<Timestamp> for Timestamp

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

This method tests for self and other values to be equal, and is used by ==.
