@jokemanfire I appreciate you taking on this work very much.
Why don't we directly reopen #173 and continue the work?
Just let me know if there are any difficulties.

Thanks agian.

Thanks agian.

There are some conflicts and API changes that need to be resolved and some code needs to be packaged to adapt to the current API. It's not easy to operate with the previous version of PR. I need to add some commit to complete this feature. I have communicated with the original author.

Nice work, thanks @jokemanfire! Could you cleanup your commits? It makes us easier to review and maintain.

1. Use git rebase instead of git merge.
2. Modify the commit title to {subsystem}: {brief title for your changes}, and give it a brief introduction in the commit message.
3. Split your commits, and don't mix bugfixes, refactoring and new features.
4. Please modify this PR title to something like "codegen: Introduce a new codegen using prost".

Thanks!

I have changed it.

Once this feature gets merged, I prefer to bump a major version to 2 to avoid some compatibility issues, as it nearly changes the entire codegen engine. WDYT? @jokemanfire @Tim-Zhang

Once this feature gets merged, I prefer to bump a major version to 2 to avoid some compatibility issues, as it nearly changes the entire codegen engine. WDYT? 一旦这个功能合并，我更倾向于将主版本号提升到 2，以避免一些兼容性问题，因为它几乎改变了整个代码生成引擎。你怎么看？@jokemanfire @Tim-Zhang

This modification is indeed quite significant, and I agree. It depends on the maintainer's thoughts
