Trait for geometric state persistence.

Implementations may target different backends:

• MemoryStore: In-memory (for testing)
• IndexedDbStore: Browser IndexedDB (for WASM)
• FileStore: File system (for native)

Required Methods

fn save_snapshot(&mut self, state: &GA3, clock: &VectorClock)

Save a state snapshot.

fn load_latest_snapshot(&self) -> Option<Snapshot>

Load the latest snapshot.

fn load_snapshot(&self, id: u64) -> Option<Snapshot>

Load a specific snapshot by ID.

fn append_operation(&mut self, delta: StateDelta)

Append an operation to the log.

fn operations_since(&self, clock: &VectorClock) -> Vec<StoredOperation>

Get all operations since a given clock.

fn operations_since_sequence(&self, sequence: u64) -> Vec<StoredOperation>

Get all operations since a given sequence number.

fn compact(&mut self) -> Option<Snapshot>

Compact the operation log by creating a new snapshot.

Operations before the snapshot can be discarded.

fn stats(&self) -> StorageStats

Get storage statistics.

fn clear(&mut self)

Clear all stored data.
