  # GitLab CI can only cache data that resides in /builds/ and /cache/
  # directories[1]. Both of these locations are *not* writeable to non-privileged
  # users, but the project directory (the Git workdir) is — it's
  # world-writeable. So we ask Cargo to put its caches inside the Git workdir,
  # and install binaries (e.g. cargo-sweep) in there too.
