Struct ProvenanceEvent 

pub struct ProvenanceEvent {
    pub provenance_uuid: Uuid,
    pub operation_uuid: Uuid,
    pub event_kind: EventKind,
    pub actor_uuid: Option<Uuid>,
    pub recorded_at_micros: i64,
    pub contract_version: u32,
}

One immutable provenance event.

Fields

provenance_uuid: Uuid

Deterministic UUIDv8 derived from the canonical event.

operation_uuid: Uuid

Caller transaction/idempotency identity.

event_kind: EventKind

Closed event kind.

actor_uuid: Option<Uuid>

Optional analyst/agent identity.

recorded_at_micros: i64

Injected UTC transaction timestamp in microseconds.

contract_version: u32

Event record contract.

Implementations

impl ProvenanceEvent

pub fn new( operation_uuid: Uuid, event_kind: EventKind, actor_uuid: Option<Uuid>, recorded_at_micros: i64, ) -> Result<Self, ProvenanceError>

Build and identify one canonical event.

Errors

Rejects nil operation/actor UUIDs or canonical encoding failures.

pub fn canonical_bytes(&self) -> Result<Vec<u8>, ProvenanceError>

Canonical bytes used for fingerprints and idempotency comparison.

Errors

Returns a canonical encoding failure if shared bounds are exceeded.

pub fn fingerprint(&self) -> Result<[u8; 32], ProvenanceError>

Full domain-separated event fingerprint.

Errors

Returns a canonical encoding failure if shared bounds are exceeded.
