Struct StoreHooks 

pub struct StoreHooks {
    pub redaction: Option<SharedEventRedactor>,
    pub event_signer: Option<SessionSigner>,
    pub receipt_signer: Option<SessionSigner>,
    pub retention: RetentionPolicy,
    pub archive_sink: Option<SharedArchiveSink>,
}

Optional processors a host can plug in. Mutation hooks run inline before persistence; redaction is also reapplied to public retrieval projections as defense in depth for older stored data.

Fields

redaction: Option<SharedEventRedactor>

Applied to event payloads and headers before persistence and again when events are read, snapshotted, or replayed.

event_signer: Option<SessionSigner>

If set, every event is signed at append time. Without a signer only the Receipt event minted by SessionStore::close is signed (which is enough to verify the chain end-to-end).

receipt_signer: Option<SessionSigner>

Required to mint receipts on close. Without this, close still finalises the chain root hash but emits an unsigned Receipt event.

retention: RetentionPolicy

Default retention policy applied to new sessions when their meta does not override it.

archive_sink: Option<SharedArchiveSink>

Optional durable archive destination. The default SessionStore::sweep_retention writes archived sessions and tombstones here before the rows leave primary storage; see super::retention::ArchiveSink.
