Struct Snapshot 

pub struct Snapshot<Pos, Data> {
    pub position: Pos,
    pub data: Data,
}

Point-in-time snapshot of aggregate state.

The position field indicates the event stream position when this snapshot was taken. When loading an aggregate, only events after this position need to be replayed.

Schema evolution is handled at the serialisation layer (e.g., via serde_evolve), so no version field is needed here.

Type Parameters

• Pos: The position type used by the event store (e.g., u64, i64, etc.)
• Data: The snapshot payload type.

Fields

position: Pos

Event position when this snapshot was taken.

data: Data

Snapshot payload.
