error[E0277]: `Urgent` is not a publish transform for `ForReply` writing `()`

   = note: a transform states its position by the kind it implements: `PublishTransform<K>` for every `K: ContextKind` mounts anywhere, `PublishTransform<ForReply<C>>` reads the delivery and mounts on a reply, `PublishTransform<ForSlot>` mounts on an `Out` slot. A slot publish is issued by the handler body, so it has no delivery to hand on
   = note: a transform also states the broker's per-message options it writes, and mounts only over a publisher whose `Publisher::Options` is that type: `()` here. One that writes none is generic over them - `impl<K: ContextKind, Options> PublishTransform<K, Options> for ..` - and mounts anywhere
help: the trait `PublishTransform<ForReply, ()>` is not implemented for `Urgent`
      but trait `PublishTransform<ForReply, Priority>` is implemented for it
