This example repository generates rust code to represent the protocol buffer
data structure defined in src/protos/example.proto.
Since the most recent update to rust-analyzer type recognition of these
structures has failed with no noticeable errors beyond annotations and
suggestions being missing.
This should be as simple as cargo run to verify the generated code functions
at compile time.
Once these files have been generated I would expect rust-analyzer to index them
and produce type hints in the IDE.
Please see included screenshot of how this displays on VSCode.
