pub struct EventSubscriptionService { /* private fields */ }
Expand description

The subscription service offered by state sync, responsible for notifying subscribers of on-chain events.

Implementations

Returns an EventNotificationListener that can be monitored for subscribed events. If an event key is subscribed to, it means the EventNotificationListener will be sent a notification every time an event with the matching key occurs on-chain. Note: if the notification buffer fills up too quickly, older notifications will be dropped. As such, it is the responsibility of the subscriber to ensure notifications are processed in a timely manner.

Returns a ReconfigNotificationListener that can be monitored for reconfiguration events. Subscribers will be sent a notification containing all new on-chain configuration values whenever a new epoch begins. Note: if the notification buffer fills up too quickly, older notifications will be dropped. As such, it is the responsibility of the subscriber to ensure notifications are processed in a timely manner.

Trait Implementations

Notify the subscription service of the events at the specified version.

Forces the subscription service to notify subscribers of the current on-chain configurations at the specified version. This is useful for forcing reconfiguration notifications even if no reconfiguration event was processed (e.g., on startup). Read more
