pub fn changes(before: &Config, plan: &SetupPlan) -> Vec<String>Expand description
A human-readable list of what this plan changes against before, for the
review screen. Empty means nothing would change.
Credentials are described as “set” / “changed” / “cleared” and never printed - the review screen is exactly the moment a shoulder-surfer is looking, and a key the user cannot read back is not a real loss when the wizard just verified it works.
