type t
val equal : t -> t -> bool
val hash : t -> int
val compare : t -> t -> int
val show : t -> string
val pretty : unit -> t -> Goblint_lib.Printable.Pretty.doc
val printXml : 'a BatInnerIO.output -> t -> unit
val name : unit -> string
val to_yojson : t -> Yojson.Safe.t
val tag : t -> int

Unique ID, given by HConsed, for context identification in witness

val arbitrary : unit -> t QCheck.arbitrary
val relift : t -> t
val leq : t -> t -> bool
val join : t -> t -> t
val meet : t -> t -> t
val widen : t -> t -> t

widen x y assumes leq x y. Solvers guarantee this by calling widen old (join old new).

val narrow : t -> t -> t
val pretty_diff : unit -> (t * t) -> Goblint_lib.Lattice.Pretty.doc

If leq x y = false, then pretty_diff () (x, y) should explain why.
