Module `Verification.Conditions`Source

Generates verification conditions from scope definitions

Sourcetype verification_condition_kind =

| NoEmptyError
(*
This verification condition checks whether a definition never returns an empty error
*)
| NoOverlappingExceptions
(*
This verification condition checks whether a definition never returns a conflict error
*)

Sourcetype verification_condition = {

vc_guard : Dcalc.Ast.typed Dcalc.Ast.marked_expr;
(*
This expression should have type bool
*)
vc_kind : verification_condition_kind;
vc_scope : Dcalc.Ast.ScopeName.t;
vc_variable : Dcalc.Ast.Var.t Utils.Marked.pos;
vc_free_vars_typ : Dcalc.Ast.typ Utils.Marked.pos Dcalc.Ast.VarMap.t;
(*
Types of the locally free variables in vc_guard. The types of other free variables linked to scope variables can be obtained with Dcalc.Ast.variable_types.
