DirectSequencerClientTransport

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.

  29. def performUnlessClosing[A](name: String)(f: => A)(implicit traceContext: TraceContext): UnlessShutdown[A]

    Performs the task given by f unless a shutdown has been initiated.

    Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

    DO NOT CALL this.close as part of f, because it will result in a deadlock.

    returns

    scala.None$ if a shutdown has been initiated. Otherwise the result of the task.

    Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead. Both etf and the error are lazy; etf is only evaluated if there is no shutdown, the error only if we're shutting down. The shutdown will only begin after etf completes, but other tasks may execute concurrently with etf, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingF). The tasks are assumed to take less than closingTimeout to complete.

    Performs the Future given by f unless a shutdown has been initiated. The future is lazy and not evaluated during shutdown. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingEitherT).

    The future completes with com.digitalasset.canton.lifecycle.UnlessShutdown.AbortedDueToShutdown if a shutdown has been initiated. Otherwise the result of the task wrapped in com.digitalasset.canton.lifecycle.UnlessShutdown.Outcome.

    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.
