Struct RandomIndexPack 

pub struct RandomIndexPack {
    pub partitions: Vec<PartitionLocation>,
}

The Random Index Pack — SMPTE ST 377-1:2019 §12: one PartitionLocation per Partition in the file (including Header and Footer), ascending byte_offset order, plus a trailing overall-length field (§12.2 Note 2) that lets a decoder seek from EOF directly to this Pack’s own Key without a forward scan.

Fields

partitions: Vec<PartitionLocation>

One entry per Partition in the file, ascending byte_offset order.

Implementations

impl RandomIndexPack

pub fn key() -> UlBytes

Build the 16-byte Random Index Pack Key (Table 29).

pub fn is_rip_key(key: &[u8; 16]) -> bool

True if key is the Random Index Pack Key (Table 29), ignoring byte 8 (registry version, wildcard).

pub fn parse_prefix(bytes: &[u8]) -> Result<(Self, usize)>

Parse a Random Index Pack (Key + Length + Value, including the trailing overall-length field) from bytes.

Trait Implementations

impl Clone for RandomIndexPack

fn clone(&self) -> RandomIndexPack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RandomIndexPack

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

Formats the value using the given formatter.

impl Default for RandomIndexPack

fn default() -> RandomIndexPack

Returns the “default value” for a type.

impl Eq for RandomIndexPack

impl<'a> Parse<'a> for RandomIndexPack

type Error = Error

The error type this implementer returns. Typically the enclosing crate’s Error enum.

fn parse(bytes: &'a [u8]) -> Result<Self>

Parse bytes as Self. Returns Err(Self::Error) on any protocol violation or buffer underrun.

impl PartialEq for RandomIndexPack

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for RandomIndexPack

type Error = Error

The error type this implementer returns (usually the same as the corresponding Parse impl, but need not be).

fn serialized_len(&self) -> usize

Number of bytes serialize_into will write.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize>

Write the serialised form into buf. Returns the number of bytes written (always equal to serialized_len()).

fn to_bytes(&self) -> Vec<u8>

where Self::Error: Debug,

Convenience: allocate a Vec and serialise into it.
