fn load(&mut self, aggregate_id: &str) -> Vec<EventEnvelope<A>>

Load all events for a particular aggregate_id

fn load_aggregate(&mut self, aggregate_id: &str) -> AggregateContext<A>

Load aggregate at current state

fn commit( &mut self, events: Vec<A::Event>, context: AggregateContext<A>, metadata: HashMap<String, String>, ) -> Result<Vec<EventEnvelope<A>>, AggregateError>
