Sourcetype tree

A proof tree

Sourcetype node

A proof node

Sourcemodule Node : sig ... end
Sourceval get : Wpo.t -> [ `Script | `Proof | `Saved | `None ]
Sourceval proof : main:Wpo.t -> tree
Sourceval reset : tree -> unit
Sourceval clear : Wpo.t -> unit
Sourceval validate : tree -> unit

Re-compute stats & set status of the entire script

Sourceval consolidated : Wpo.t -> Stats.stats

Consolidate statistics wrt current script or prover results

Leaves are numbered from 0 to n-1

Sourcetype status = [
  1. | `Unproved
    (*

    proof obligation not proved

    *)
  2. | `Proved
    (*

    proof obligation is proved

    *)
  3. | `Pending of int
    (*

    proof is pending

    *)
  4. | `Passed
    (*

    smoke test is passed (PO is not proved)

    *)
  5. | `Invalid
    (*

    smoke test has failed (PO is proved)

    *)
  6. | `StillResist of int
    (*

    proof is pending

    *)
