trait SequencerSubscription[HandlerError] extends FlagCloseableAsync with NamedLogging
A running subscription to a sequencer. Can be closed by the consumer or the producer. Once closed the closeReason value will be fulfilled with the reason the subscription was closed. Implementations are expected to immediately start their subscription unless otherwise stated. If close is called while the handler is running closeReason should not be completed until the handler has completed.

Future which is completed when the subscription is closed. If the subscription is closed in a healthy state the future will be completed successfully. However if the subscription fails for an unexpected reason at runtime the completion should be failed.
