Struct NullResolver

pub struct NullResolver<R> { /* private fields */ }

A resolver that implements implements Resolve+HostResolve but returns NameNotFound on resolve

This is needed to add resolver that can only resolve hostnames to the router.

You can create it with HostResolve::null_service_resolver
