Struct Pcr 

pub struct Pcr {
    pub base: u64,
    pub extension: u16,
}

Program Clock Reference (ISO/IEC 13818-1:2007 §2.4.3.5): a 33-bit base on a 90 kHz clock plus a 9-bit extension on a 27 MHz clock.

Fields

base: u64

33-bit base (90 kHz units).

extension: u16

9-bit extension (27 MHz units).

Implementations

impl Pcr

pub fn as_27mhz(self) -> u64

Full PCR value on the 27 MHz clock: base * 300 + extension.

ISO/IEC 13818-1:2007 §2.4.3.5: PCR = PCR_base * 300 + PCR_ext.

pub fn from_27mhz(ticks: u64) -> Self

Construct a Pcr from an absolute 27 MHz clock value.

Decomposes ticks into base = ticks / 300 and extension = ticks % 300, clamping each to its wire width (33-bit base, 9-bit extension) — ISO/IEC 13818-1:2007 §2.4.3.5.

Round-trips with as_27mhz: Pcr::from_27mhz(p.as_27mhz()) == p for any valid Pcr.

pub fn to_field_bytes(self) -> [u8; 6]

Encode as the exact 6-byte PCR/OPCR field used in the adaptation field (ISO/IEC 13818-1:2007 §2.4.3.5).

Wire layout (big-endian, 48 bits): [base[32:25]][base[24:17]][base[16:9]][base[8:1]][base[0] | 6×reserved(1) | ext[8]][ext[7:0]]

The 6 reserved bits are set to 1 as per the spec’s “reserved” convention. Exact inverse of the private parse function.

Trait Implementations

impl Clone for Pcr

fn clone(&self) -> Pcr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Pcr

impl Debug for Pcr

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

Formats the value using the given formatter.

impl Eq for Pcr

impl PartialEq for Pcr

fn eq(&self, other: &Pcr) -> 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 Pcr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
