No, there isn't! There is only the GitHub Actions version for the follow-up.

Thanks for sharing this, found it useful. It was my 4th highest result of googling circleci caching rust.

A few notes if anyone else ever reads this:

  • Since our project is using cargo build --release in one step, we are caching directories in both target/debug/ and target/release/.

  • I considered saving the cache after the testing step, but IMO that just took too long to upload the cache.

  • To avoid having the value of the caching key specified in multiple places (i.e. checksum "Cargo.lock"), I relied on one of CircleCI's reusability mechanisms (namely the parameters one).
