class DirectSequencerClientTransport extends SequencerClientTransport with NamedLogging
This transport is meant to be used to create a sequencer client that connects directly to an in-process sequencer. Needed for cases when the sequencer node itself needs to listen to specific events such as identity events.

Create a single subscription to read events from the Sequencer for this member starting from the counter defined in the request. Transports are currently responsible for calling the supplied handler. The handler must not be called concurrently and must receive events in-order. If the handler fails with an exception the subscription should close with a com.digitalasset.canton.sequencing.client.SubscriptionCloseReason.HandlerError. If the subscription fails for a technical reason it should close with a com.digitalasset.canton.sequencing.client.SubscriptionCloseReason.SubscriptionError. The transport is not expected to provide retries of subscriptions.
