Module error 

HTTP error domain.

HttpError is the open trait every domain error implements; HttpException is the type-erased box that handlers actually return. The framework’s stock errors (NotFound, Unauthorized, BadRequest, Validation, ServiceUnavailable, Conflict, TooManyRequests, Internal) all implement HttpError and gain From<…> for HttpException automatically, so handlers compose with ? regardless of which concrete error variant they construct.
