Struct ProtectionError 

pub struct ProtectionError { /* private fields */ }

Available on crate feature csrf only.

Reason a request was rejected by Csrf.

Retrieve the category with ProtectionError::kind. Csrf attaches it to every 403 Forbidden rejection response’s extensions so surrounding layers can distinguish explicit cross-origin rejections from conservative fallback rejections.

This is an opaque struct rather than an enum so future variants can carry additional context without a breaking change; match on kind instead.
