Function check_with_custom_deny 

pub fn check_with_custom_deny<F, Args, P1, P1Args>(
    route: Route,
    perm: P1,
    handler: F,
    deny_handler: fn(HttpRequest) -> HttpResponse,
) -> Route
where
    F: Handler<Args>,
    Args: FromRequest + 'static,
    P1: Permission<P1Args>,
    P1Args: FromRequest + 'static,
    F::Output: Responder,

👎Deprecated since 2.0.0-beta.1: please use permission() instead

Creates a more flexible route than check, which:

• intercepts requests and validates inputs.
• if permission checks are all true, passes through to handler.
• if any of the permissions is false, deny_handler is called.
