Struct PrimerPack 

Source
pub struct PrimerPack {
    pub entries: Vec<(u16, UlBytes)>,
}
Expand description

The Primer Pack — SMPTE ST 377-1:2019 §9.2, Tables 13-15: a Batch of {local_tag: u16, uid: AUID} entries, scoped to the single Partition that contains it (§9.2 — never accumulated across Partitions).

Fields§

§entries: Vec<(u16, UlBytes)>

Every local-tag -> UL/UUID mapping in this Partition’s Header Metadata.

Implementations§

Source§

impl PrimerPack

Source

pub fn key() -> UlBytes

Build the 16-byte Primer Pack Key (Table 13).

Source

pub fn is_primer_key(key: &UlBytes) -> bool

True if key is the Primer Pack Key (Table 13), ignoring byte 8 (registry version, wildcard).

Source

pub fn resolve_ul(&self, ul: &UlBytes) -> Option<u16>

Resolve a UL/UUID to its local tag in this Primer Pack, if present. Used to decode “dyn” (dynamically-allocated-tag) properties whose static tag the spec deliberately does not fix (docs/st377-1.md’s Annex A tables) — e.g. Preface’s IsRIPPresent.

Source

pub fn resolve_tag(&self, tag: u16) -> Option<UlBytes>

Look up the UL/UUID for a local tag, if present.

Source

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

Parse a Primer Pack (Key + Length + Value) from bytes, validating the Key and consuming exactly one KLV item’s worth. Also usable in a stream context via the returned consumed-byte count.
