Struct SupersessionReceipt 

pub struct SupersessionReceipt {
    pub superseding_id: RecordId,
    pub superseding_recorded_time: DateTime<Utc>,
    pub superseded: SupersessionTarget,
    pub superseding_digest: String,
    pub superseded_digest: String,
    pub receipt_digest: String,
}

Receipt for a supersession event.

Cryptographically identifies both the superseded record and the superseding record, providing an auditable chain of custody.

Fields

superseding_id: RecordId

ID of the record that superseded another.

superseding_recorded_time: DateTime<Utc>

Recorded time of the superseding record.

superseded: SupersessionTarget

The target that was superseded.

superseding_digest: String

SHA-256 digest of the superseding record content (for integrity verification).

superseded_digest: String

SHA-256 digest of the superseded record content (for integrity verification).

receipt_digest: String

SHA-256 digest of the receipt itself (self-checksum).

Implementations

impl SupersessionReceipt

pub fn new<T>( superseded: BitemporalRecord<T>, superseding: BitemporalRecord<T>, ) -> Self

where T: Serialize,

Create a new supersession receipt from superseded and superseding records.

The receipt is the cryptographic audit handle for a supersession event. The digests bind all content of both records (id, temporal fields, AND the JSON-serialized value) so that two records differing only in their value produce different digests. The receipt_digest additionally binds the two record digests so the supersession relationship is itself tamper-evident.
