These crates are superseded by https://github.com/googleapis/google-cloud-rust

You should prefer the official client library provided by Google: https://github.com/googleapis/google-cloud-rust, and I will try to shut down maintenance here to the point where the project is archived.

This can happen gradually.

Q & A

What about the CLI programs

They have been untested and I am not sure they work at all. Maybe they are still useful to you though as a way to try out the API programmatically.

I like these generated crates and want to use them, still

That's alright, too. At some point you might have to maintain your own copy of the generated google crate code if that's alright for you. In the end it's all just HTTP, and an ever-changing API landscape on Google's side to keep up with.
