class resolve_to_any_obj_channel :This resolver calls the function?close:Netchannels.in_obj_channel -> unit -> channel_of_id:(Pxp_core_types.I.resolver_id -> accepted_id) -> unit ->resolver
channel_of_id to open a new channel for
the passed resolver_id. This function must either return the accepted_id,
or it must fail with Not_competent.
When the resolver is closed, the function passed by the close
argument is called. By default, the channel is closed
(i.e. the default is: close:(fun ch -> ch # close_in)).
