cache:
  # Don't use `cache: cargo` since it adds the `target` directory and that can be huge.
  # Saving and loading this directory dwarfes actual compilation and test times. But what is more
  # important, is that travis timeouts the build since the job doesn't produce any output for more
  # than 10 minutes.

  # So we just cache ~/.cargo directory
