Class type

Declare data from the host application that is opaque (no syntax), like int but not like list or pair

type doc = string

type name = string

type 'a declaration = {

name : name;
doc : doc;
pp : Format.formatter -> 'a -> unit;
eq : 'a -> 'a -> bool;
hash : 'a -> int;
hconsed : bool;
constants : (name * 'a) list;

}

The eq function is used by unification. Limitation: unification of * two cdata cannot alter the constraint store. This can be lifted in the * future if there is user request. * * If the hconsed is true, then the readback function is * automatically hashcons the data using the eq and hash functions.

val declare : 'a declaration -> 'a Conversion.t
