Struct ErrorBag 

pub struct ErrorBag { /* private fields */ }

Per-field validation messages, each a locale-free Text. Empty means valid. Whoever renders the bag localizes each message at its sink: the admin form through the request translator, the API into a localized 422 body.

Every field with messages, in field order, each with its messages.
