Struct ProvenanceSidecar 

pub struct ProvenanceSidecar {
    pub source_bytes: Vec<u8>,
    pub source_media_type: String,
    pub licence: String,
    pub vc: Vec<u8>,
    pub semantic_metadata: Vec<u8>,
    pub timestamp_epoch_s: u64,
    pub version_hash: [u8; 32],
}

An owned provenance sidecar to bundle into a .10d — the source bytes an asset was derived from, their media type, the licence (required), and an optional verifiable credential.

Fields

source_bytes: Vec<u8>

The immutable original bytes the asset was derived from.

source_media_type: String

The source’s media type (e.g. model/gltf-binary, text/markdown).

licence: String

The licence the source is available under (e.g. CC-BY-4.0, CC0). Required — a provenance record with no licence is a stripped context.

vc: Vec<u8>

An optional verifiable credential (CBOR / JWT bytes) attesting the derivation chain. Empty = none.

semantic_metadata: Vec<u8>

Schema.org / Dublin Core semantic CBOR-LD metadata payload.

timestamp_epoch_s: u64

Creation or harvest timestamp (UNIX epoch seconds).

version_hash: [u8; 32]

Cryptographic version control hash (e.g., SHA256 of the git commit or asset).

Implementations

impl ProvenanceSidecar

pub fn new( source_bytes: impl Into<Vec<u8>>, source_media_type: impl Into<String>, licence: impl Into<String>, ) -> Self

pub fn with_vc(self, vc: impl Into<Vec<u8>>) -> Self

pub fn with_metadata( self, metadata: impl Into<Vec<u8>>, timestamp: u64, hash: [u8; 32], ) -> Self

pub fn source_digest(&self) -> u32

The CRC-32C digest of the source bytes — the value stored in the header and re-checked by validate_provenance.

Trait Implementations

impl Clone for ProvenanceSidecar

fn clone(&self) -> ProvenanceSidecar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProvenanceSidecar

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

Formats the value using the given formatter.

impl Default for ProvenanceSidecar

fn default() -> ProvenanceSidecar

Returns the “default value” for a type.

impl PartialEq for ProvenanceSidecar

fn eq(&self, other: &ProvenanceSidecar) -> 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.
