Z integers with an additional top element.

  • before 33.0-Arsenic

    was named Int_Base.

include Datatype.S with type t = Z.t Lattice_bounds.or_top
include Datatype.S_no_copy with type t = Z.t Lattice_bounds.or_top
include Datatype.Ty with type t = Z.t Lattice_bounds.or_top
val ty : t Type.t
val datatype_name : string

Unique name of the datatype.

val datatype_descr : t Descr.t

Datatype descriptor.

val packed_descr : Structural_descr.pack

Packed version of the descriptor.

val reprs : t list

List of representants of the descriptor.

val equal : t -> t -> bool

Equality: same spec than Stdlib.(=).

val compare : t -> t -> int

Comparison: same spec than Stdlib.compare.

val hash : t -> int

Hash function: same spec than Hashtbl.hash.

val pretty : Stdlib.Format.formatter -> t -> unit

Pretty print each value in an user-friendly way.

val mem_project : (Project_skeleton.t -> bool) -> t -> bool

mem_project f x must return true iff there is a value p of type Project.t in x such that f p returns true.

val copy : t -> t

Deep copy: no possible sharing between x and copy x.

val top : t
val of_int : int -> t
val is_zero : t -> bool
val is_top : t -> bool
val inject : Z.t -> t
val project : t -> Z.t
  • raises Error_Top

    if the argument is Top.
