Each configuration option is either stable or unstable.
Stable options can be used directly, while unstable options are opt-in.
To enable unstable options, set `unstable_features = true` in `rustfmt.toml` or pass `--unstable-options` to rustfmt,
and ensure that the environment variable `CFG_RELEASE_CHANNEL` is set to `nightly`.
To enable unstable options, set `unstable_features = true` in `rustfmt.toml` or pass `--unstable-options` to rustfmt.
