Struct SourceRecord 

#[non_exhaustive]
pub struct SourceRecord {
    pub source: ProviderId,
    pub ids: Vec<WorkId>,
    pub work: Work,
    pub fields: FieldSet,
    pub raw: Raw,
    pub fetched_at: Timestamp,
}

One provider’s view of one work. Providers never merge records; the engine does, keeping each SourceRecord as the recomputable source of truth.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

source: ProviderId

ids: Vec<WorkId>

Every identifier the provider asserts for this work, its own native ID first. These are the edges of the identifier graph.

work: Work

fields: FieldSet

The fields this record is authoritative for. A None inside a covered field means “the provider has no value”, not “not asked”. The cache serves a request from this record iff the request’s fields are a subset.

raw: Raw

fetched_at: Timestamp

Implementations

impl SourceRecord

pub fn new( source: ProviderId, ids: Vec<WorkId>, work: Work, fields: FieldSet, raw: Raw, fetched_at: Timestamp, ) -> Self

fetched_at is passed in rather than read here: core doesn’t touch the clock, which keeps it deterministic in tests and portable to WASM.

pub fn native_id(&self) -> Option<&WorkId>

The provider’s own identifier for the work, if it gave any.
