Struct EssenceContainerData 

pub struct EssenceContainerData {
    pub interchange: InterchangeObjectFields,
    pub linked_package_uid: PackageId,
    pub index_sid: Option<u32>,
    pub body_sid: u32,
    pub dark: Vec<(u16, Vec<u8>)>,
}

The Essence Container Data Set — SMPTE ST 377-1:2019 Annex A.5: links a LinkedPackageUID to the BodySID/IndexSID pair identifying its Essence Container / Index Table Segments among the file’s Partitions.

The four Boolean properties A.5 defines with a “dyn” (dynamically allocated, no fixed static tag) local tag — PrecedingIndexTable, SingularPartitionUsage, FollowingIndexTable, IsSparse — are preserved byte-for-byte in dark rather than individually typed in this first pass, per docs/st377-1.md’s Scope section.

Fields

interchange: InterchangeObjectFields

Interchange Object (A.1) base properties.

linked_package_uid: PackageId

Linked Package UID (0x2701, Req) — the Package this Set is linked to (opaque UMID, see docs/st377-1.md’s Scope section).

index_sid: Option<u32>

IndexSID (0x3F06, Opt) — ID of the Index Table for the linked Essence Container, if any.

body_sid: u32

BodySID (0x3F07, Req) — ID of the linked Essence Container (0 = external to the file).

dark: Vec<(u16, Vec<u8>)>

Every other property found on parse, including the four “dyn”-tagged Boolean properties above and any private/dark extension — preserved byte-for-byte, not decoded.

Trait Implementations

impl Clone for EssenceContainerData

fn clone(&self) -> EssenceContainerData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EssenceContainerData

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

Formats the value using the given formatter.

impl Eq for EssenceContainerData

impl<'a> Parse<'a> for EssenceContainerData

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 EssenceContainerData

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for EssenceContainerData

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.
