Hey Endre,
Thanks for the response but I don't quite understand how to implement what
you're suggesting. I did find the Fold class but it has no Promise/Future
in it. I also found the FoldSink class but the only way to get a future
back from that is to use the attach method and I've no idea how to get that
into my flow. Any example how to do this?
Here's what I'm working with currently:
val connection = StreamTcp().outgoingConnection(address)
val handler: Flow[ByteString, ByteString] =
Flow[ByteString].mapConcat(frameReconciler.reconcile)
.map(decodeRequest).map(handleRequest).map(encodeResponse).map(createFrame)
connection.handleWith(handler)
Best regards,
Cole
