Trait for durable storage backends

Implement this trait to persist DurableState across crashes.

Required Methods

fn persist(&mut self, state: &DurableState<S>) -> Result<(), StorageError>

Persist the durable state

fn load( &self, replica_id: &str, ) -> Result<Option<DurableState<S>>, StorageError>
