Is there any reason we are using this instead of just @actions/cache or some Rust configured one? Or is this doing something else?

[aleksrutins]

I think that that's specifically for the docker run tests, to cache built Docker layers between runs. I'm not sure that @actions/cache can do that, and if it can, it's probably a good bit more complicated.

[coffee-cup]

Yes @aleksrutins is correct. It simply just caches the Docker layers and does not have anything to do with the Rust cache.

However, it has been causing some issues lately so I might remove it.
