Trait Implementations

impl EventStore for PostgresEventStore

fn load_events<'life0, 'async_trait>( &'life0 self, aggregate_id: Uuid, from_version: u64, ) -> Pin<Box<dyn Future<Output = Result<Vec<StoredEvent>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Load events for an aggregate starting after from_version. Pass 0 to load all events.

fn append<'life0, 'life1, 'async_trait>( &'life0 self, aggregate_id: Uuid, aggregate_type: &'life1 str, expected_version: u64, events: Vec<NewEvent>, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Append events with optimistic concurrency check. Returns the new version (sequence of the last appended event).

fn exists<'life0, 'async_trait>( &'life0 self, aggregate_id: Uuid, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Check if an aggregate exists (has any events).
