class type 'a persistent = object ... end

val with_persistence : 
  'a persistent ->
  ('impl -> 'a Capability.t) ->
  {Untyped}1.generic_service as 'impl ->
  'a Capability.t

with_persistence persist Service.Foo.local obj is like Service.Foo.local obj, but the resulting service also handles the Cap'n Proto persistence protocol, using persist.

val with_sturdy_ref : 
  'a Sturdy_ref.t ->
  ('impl -> 'a Capability.t) ->
  {Untyped}1.generic_service as 'impl ->
  'a Capability.t

with_sturdy_ref sr Service.Foo.local obj is like Service.Foo.local obj, but responds to save calls by returning sr.

val save : 
  'a Capability.t ->
  (Uri.t, [> `Capnp of Capnp_rpc.Error.t ]) Lwt_result.t

save cap calls the persistent save method on cap. Note that not all capabilities can be saved. todo: this should return an 'a Sturdy_ref.t; see Sturdy_ref.reader.

val save_exn : 'a Capability.t -> Uri.t Lwt.t

save_exn is a wrapper for save that returns a failed thread on error.
