Original GitHub issue: https://github.com/AppFlowy-IO/AppFlowy/issues/114

Describe the bug
While building Appflowy on linux, doing the optional protobuf generation will not generate the proper output. The repository already has some tracked protobuf files with which the app works as of now (ie., without generating the protobuf and using already existing ones ). Developers who want to work on rust in Appflowy will not be able to build the app after making changes

To Reproduce
Follow the steps mentioned here including the optional protobuf generation step (step 9).

Logs
When trying to build appflowy rust sdk after protobuf generation, the following errors occur:

error: could not compile flowy-document-infra due to 4 previous errors
warning: build failed, waiting for other jobs to finish...
error: build failed
[cargo-make] ERROR - Error while executing command, exit code: 101
[cargo-make] WARN - Build Failed.

Expected behavior
Protobuf generation should generate proper output, more or less very similar to the already tracked generated files.

The screenshot below shows the changes (tracked by git) that will take place after the protobuf generation step

The changes in every file other than derive_cache.rs are indentation and comment changes. So, the problem can be narrowed down to this file shown above.
