Struct SnapshotRecord

Source

pub struct SnapshotRecord<S> {
    pub sequence: usize,
    pub state: S,
    pub recorded_at: DateTime<Utc>,
    pub first_recorded_at: DateTime<Utc>,
}

Expand description

A persisted snapshot as loaded: the state plus the metadata of the events it summarises.

Fields§

§sequence: usize

Events 1..=sequence are folded into state.

§state: S§recorded_at: DateTime<Utc>§first_recorded_at: DateTime<Utc>

recorded_at of event 1 — keeps entity_first_persisted_at() O(1).
