- anki._backend stores the protobuf files and rsbackend.py code
- pylib modules import protobuf messages directly from the
_pb2 files, and explicitly export any will be returned or consumed
by public pylib functions, so that calling code can import from pylib
- the "rsbackend" no longer imports and re-exports protobuf messages
- pylib can just consume them directly.
- move errors to errors.py
Still todo:
- rsbridge
- finishing the work on rsbackend, and check what we need to add
back to the original file location to avoid breaking add-ons
In protobuf "...enum values use C++ scoping rules, meaning that
enum values are siblings of their type, not children of it.
Therefore, [an enum variant] must be unique within [a message],
not just within [the enum.]"
So we must prefix enum variants with their enum's name, but can
also call them directly from the message namespace.
The protobuf crate is smart, though, and strips the prefixes.
(Simultaneously change some SearchTerm variant names.)
