val add_cb : t -> name:string -> callback -> unit

val evalj : t -> json -> json option

evalj srv json_in generates a return value for the given JSON-RPC request json_in for the server srv. If no answer is to be sent back to the caller, this function will return None.

val eval : t -> string -> string option

eval srv s works just like evalj srv json but will parse the value s to JSON; it also converts the reply to a string value to be sent back to the caller.
