Allows a member to acknowledge that they have read all events up to and including the provided timestamp, and that they will never re-read these events again. This information is currently only used for informational purposes and to provide a watermark for which it is safe to prune earlier events from the sequencer data stores. There is no requirement for every event to be individually acknowledged, and in fact callers are encouraged to only periodically record acknowledgements (at an interval of minutes is expected to be more than sufficient for pruning).

Newer version of acknowledgements. To be active for protocol versions >= 4. The argument here is an AcknowledgeRequest wrapped in SignedContent. The signature is checked on the server side to avoid that malicious sequencers create fake acknowledgements in multi-writer architectures where writers don't fully trust each other.

Blocks until all earlier tasks have completed and then prevents further tasks from being run.

Check whether we're closing. Susceptible to race conditions; unless you're using using this as a flag to the retry lib or you really know what you're doing, prefer performUnlessClosing and friends.

track running futures on shutdown

set to true to get detailed information about all futures that did not complete during shutdown. if set to false, we don't do anything.

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.

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.

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

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 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.

Register a task to run when shutdown is initiated.

You can use this for example to register tasks that cancel long-running computations, whose termination you can then wait for in "closeAsync".

Submit a send request to the sequencer for sequencing asynchronously. The rpc request may return an error if the request cannot be processed at all - see SendAsyncResponse for these scenarios. The sequencer may emit a Deliver or DeliverError event from this send, if the subscriber witnesses an event greater or equal to the supplied maxSequencingTime, the sequencer guarantees not to publish a future Deliver event for this send. The sequencer implementation may however publish a future DeliverError (typically used to indicate maxSequencingTime exceeded).

Newer version of request submission (for authenticated members). To be active for protocol versions >= 4. The argument here is a SubmissionRequest wrapped in SignedContent. The signature is checked on the server side to avoid that malicious sequencers create fake submission requests in multi-writer architectures where writers don't fully trust each other.

Submit a send request to the sequencer for sequencing asynchronously exactly like SendAsync, except that this meant to be used only by unauthenticated members for very specific operations that do not require authentication such as requesting that a participant's topology data gets accepted by the topology manager

Establishes a stream with the server to receive sequenced events from the domain after the given counter. The delivered events will have a sequential counter and monotonically increasing timestamp. TBD: Message TTL - How far back should it go when the participant initiate a subscription ?

Establishes a stream with the server to receive sequenced events exactly like Subscribe, except that this is supposed to be used only by unauthenticated members similarly to SendAsyncUnauthenticated
