AckLevel is used in Asynchronous write messages to determine how to react to
writes. This is useful when interacting with a connection from an actor and
needing to handle backpressure when writing large amounts of data.
If AckFailure is selected, WriteStatus's of "Partial" (data partially
written but buffered, next write will fail), "Zero" (no data was written,
buffer full), and "Failed" (error, probably disconnected) will generate
WriteAck messages.
If AckSuccess is selected, "Partial" and "Success" (data fully written) will
generate WriteAck
The simplest approach is to AckAll and only send ByteStrings one at a time,
waiting for the WriteAck message each time. The highest-throughput approach
is to use AckFailure, and send messages as fast as possible, but be aware that
you will be entirely responsible for resending failed messages.
WriteAck Messages are only sent to the ConnectionHandler's watcher (if one
exists, see the WatchedHandler trait), which may NOT necessarily be the
sender of the message.
If you receive a Partial status, you should not send any more data until receiving a ReadyForData message
