Specs

push(GenServer.server(), [raw_message()] | raw_message()) :: :ok

Push messages received over the reader or consumer connection into the GenStage processing pipeline for handling and acknowledgement. This is normally handled automatically by the websocket connection but can also be called directly for testing the receive pipeline.
