Struct Snapshot 

pub struct Snapshot {
    pub id: Uuid,
    pub execution_id: ExecutionId,
    pub at_sequence: EventSequence,
    pub state: Value,
    pub created_at: DateTime<Utc>,
}

A point-in-time snapshot of workflow state.

Current state = latest snapshot + events with sequence > snapshot.at_sequence

Fields

id: Uuid

execution_id: ExecutionId

at_sequence: EventSequence

The event sequence number at which this snapshot was taken.

state: Value

Materialized workflow state at this point.

created_at: DateTime<Utc>
