Trait for state storage backends.

This trait abstracts the storage of execution state, receipts, and event logs, allowing for different storage backends (filesystem, S3, GCS, etc.).

Required Methods

fn save_state(&self, state: &ExecutionState) -> Result<()>

Save execution state to storage

fn load_state(&self) -> Result<Option<ExecutionState>>

Load execution state from storage, returns None if not found

fn save_receipt(&self, receipt: &Receipt) -> Result<()>

Save receipt to storage

fn load_receipt(&self) -> Result<Option<Receipt>>

Load receipt from storage, returns None if not found

fn save_events(&self, events: &EventLog) -> Result<()>

Save event log to storage

fn load_events(&self) -> Result<Option<EventLog>>

Load event log from storage, returns None if not found

fn clear(&self) -> Result<()>

Clear all state (state.json, receipt.json, events.jsonl)

Provided Methods

fn validate_version(&self, version: &str) -> Result<()>

Validate schema version
