To learn more, run the command again with --verbose.

Turns out that Display wasn't implemented for enums and I needed to manually run cargo update -p rustfmt-config_proc_macro to make it compile again because it still used 0.1.0 version of the proc macro from the lockfile.

That seems like it was breaking change and the fix was somewhat hard to find so it'd be good to release a patch release with this, assuming someone else uses Rustfmt-as-a-library except RLS 😛

Ugh, this is a sloppy mistake. Thanks!
