Note: This is an API breaking change.
Currently the
Timestamp
value is being dropped as part of the conversion fromBorrowedMessage
toOwnedDeliveryResult
, however this value is updated once the message has been published and callers should have access to the updated value. As far as I can tell, this is the only other value that is updated as part of publishing.An alternative to expanding the tuple would be to replace it with a struct. This is a bit more disruptive now, but would make adding values in the future a backwards compatible change. So it depends how likely it is that there will be further new values.
This could also be done in a way that isn't a breaking change, but would involve duplicating functions and copying some types, i.e.
DeliveryFuture
. It doesn't seem like that level of complexity is justified given the pre 1.0 status.
