Low level module for OpaqueData

type name = string
type doc = string
type t
type 'a declaration = 'a OpaqueData.declaration = {
  1. name : name;
  2. doc : doc;
  3. pp : Stdlib.Format.formatter -> 'a -> unit;
  4. compare : 'a -> 'a -> int;
  5. hash : 'a -> int;
  6. hconsed : bool;
  7. constants : (name * 'a) list;
}

If the data_hconsed is true, then the cin function below will automatically hashcons the data using the eq and hash functions.

type 'a cdata = private {
  1. cin : 'a -> Data.term;
  2. isc : t -> bool;
  3. cout : t -> 'a;
  4. name : string;
}
