[−][src]Struct postgres_es::PostgresSnapshotStore
Storage engine using an Postgres backing and relying on a serialization of the aggregate rather than individual events. This is similar to the "snapshot strategy" seen in many CQRS frameworks.
Implementations
impl<A, E> PostgresSnapshotStore<A, E> where
A: Aggregate,
E: DomainEvent<A>, [src]
A: Aggregate,
E: DomainEvent<A>,
pub fn new(conn: Connection) -> Self[src]
Creates a new PostgresSnapshotStore from the provided database connection.
