Does it cause issues if nothing is yielded here?

Let me double check on that, thanks! Any insight on this @andrewsg?

I considered that in my review but decided it looked to me like because it's in a for loop, yielding nothing will behave identically to no rule at all, which is probably acceptable in this case. I'm not familiar with how people use this feature, however.

Gotcha, I guess it will just continue to the next rule in the list and/or end the generator if nothing is left.
I was discussing this issue with someone who pointed me to this code in the Java Bigtable client: https://github.com/googleapis/java-bigtable/blob/master/google-cloud-bigtable/src/main/java/com/google/cloud/bigtable/admin/v2/models/EncryptionInfo.java#L48 . I like the message there-- could we also have the warning suggest upgrading to a newer client version?

To the point of future proof, I think suggesting upgrading to a newer client version would make sense. Will incorporate that in!

I would say something like Unknown lifecycle rule type received: {}. Please upgrade to the latest version of google-cloud-storage.
How does that sound?

That sounds much better. Thanks for the review!

Replace python Lifecycle action parsing ValueError with a user warning in cases where the client attempts to parse unexpected fields. This will help future proof this feature by preventing runtime errors for parsing unsupported actions.
