Have you considered the ubicloud rust-cache micro-fork?

[fdr]

Ubicloud supports a more localized caching for rust artifacts. I remember Arroyo was the first to assess that the imbalance between network locality and the increase in affordable processor performance meant it was faster to recompute a bunch of compilation artifacts, rather than cache. But, that probably is not true anymore.

The way this works is you can use the ubicloud micro-fork of the rust-cache github action: https://www.ubicloud.com/docs/github-actions-integration/ubicloud-cache

If you wait around long enough, though, @velioglu will likely ship transparent caching if we can fix all the remaining problems with it, then you would be able to use any upstream action without modification.

Thanks Daniel for pointing that out! We'll give it a shot.
