Struct mpeg2ts_reader::packet::ClockRef

pub struct ClockRef { /* private fields */ }

A Clock Reference is used to represent the values of PCR and ESCR fields within the transport stream data.

A Clock Reference includes a 33-bit, 90kHz base component, together with another 9-bit, high-resolution extension component.

Together these can be viewed as a 42-bit, 27MHz quantity (e.g. let full_value = pcr as u64). Since the clock reference is limited to 33-bits, at a rate of 90kHz a continuously increasing clock value will wrap-around approximately every 26.5 hours.

Implementations

impl ClockRef

pub fn from_slice(data: &[u8]) -> ClockRef

Panics if data is shorter than 5 bytes

pub fn from_parts(base: u64, extension: u16) -> ClockRef

Panics if the base is greater than 2^33-1 or the extension is greater than 2^9-1

pub fn base(&self) -> u64

get the 33-bit, 90kHz ‘base’ component of the timestamp

pub fn extension(&self) -> u16

get the 9-bit ‘extension’ component of the timestamp, measured in 300ths of the 90kHz base clockrate (i.e. 27MHz)

Trait Implementations

impl Clone for ClockRef

fn clone(&self) -> ClockRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClockRef

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

Formats the value using the given formatter.

impl From<ClockRef> for u64

fn from(pcr: ClockRef) -> u64

Converts to this type from the input type.

impl PartialEq for ClockRef

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
