        Description copied from interface: WriteStream
        Same as but with an handler called when the operation completes

        Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.

        Specified by:
        write in interface WriteStream<K>
