Struct AssetRef 

pub struct AssetRef {
    pub uri: String,
    pub digest: u64,
    pub media_type: String,
    pub role: AssetRole,
    pub derived_from: Vec<String>,
    pub licence: Option<String>,
    pub creator: Option<String>,
}

A content-addressed reference to an asset (its stable subject is fnv60(uri), the same subject its own geometry manifest emits, so container edges join to the asset’s facts in the one identity space).

Fields

uri: String

digest: u64

Content digest (CRC-32C or SHA-256 truncated) — the anti-tamper / dedup anchor.

media_type: String

role: AssetRole

derived_from: Vec<String>

URIs of the source asset(s) this one was derived from (emits prov:wasDerivedFrom).

licence: Option<String>

Optional licence / creator (dcterms) — the never-strip-context fields.

creator: Option<String>

Implementations

impl AssetRef

pub fn new( uri: impl Into<String>, digest: u64, media_type: impl Into<String>, role: AssetRole, ) -> Self

pub fn derived_from(self, source_uri: impl Into<String>) -> Self

pub fn with_licence(self, licence: impl Into<String>) -> Self

pub fn subject(&self) -> u64

Trait Implementations

impl Clone for AssetRef

fn clone(&self) -> AssetRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssetRef

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

Formats the value using the given formatter.

impl PartialEq for AssetRef

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