Struct postgres_es::PostgresSnapshotStoreAggregateContext

pub struct PostgresSnapshotStoreAggregateContext<A> where
    A: Aggregate,  {
    pub aggregate_id: String,
    pub current_sequence: usize,
    // some fields omitted
}

Holds context for a pure event store implementation for MemStore

Fields

aggregate_id: String

The aggregate ID of the aggregate instance that has been loaded.

current_sequence: usize

The last committed event sequence number for this aggregate instance.

Trait Implementations

impl<A> AggregateContext<A> for PostgresSnapshotStoreAggregateContext<A> where
    A: Aggregate, 

fn aggregate(&self) -> &A

The aggregate instance with all state loaded.

impl<A: Aggregate> EventStore<A, PostgresSnapshotStoreAggregateContext<A>> for PostgresSnapshotStore<A>

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

Load all events for a particular aggregate_id

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

Load aggregate at current state

    &self,
    events: Vec<A::Event>,
    context: PostgresSnapshotStoreAggregateContext<A>,
    metadata: HashMap<String, String>
) -> Result<Vec<EventEnvelope<A>>, AggregateError>

Commit new events
