Enum SnapshotPolicy 

pub enum SnapshotPolicy {
    Disabled,
    EveryNEvents(i64),
}

Controls whether CommandBus maintains snapshots on the command/write rehydrate path.

Disabled is the default and reproduces the original behavior exactly: every dispatch replays the full event stream and no snapshot is ever read or written. The event log stays the immutable source of truth in both modes — a snapshot only short-circuits the rehydrate read, so enabling it can never change correctness, only the cost of loading a long-lived aggregate.

Variants

Disabled

No snapshot reads or writes; full from-zero replay on every dispatch.

EveryNEvents(i64)

Snapshot an aggregate once it has accumulated at least this many events since its last snapshot, and rehydrate from snapshot + event tail.
