Generates verification conditions from scope definitions

type verification_condition_kind =
  1. | NoEmptyError
    (*

    This verification condition checks whether a definition never returns an empty error

    *)
  2. | NoOverlappingExceptions
    (*

    This verification condition checks whether a definition never returns a conflict error

    *)
type verification_condition = {
  1. vc_guard : Shared_ast.typed Dcalc.Ast.expr;
    (*

    This expression should have type bool

    *)
  2. vc_kind : verification_condition_kind;
  3. vc_asserts : Shared_ast.typed Dcalc.Ast.expr;
    (*

    A conjunction of all assertions in scope of this VC. * This expression should have type bool

    *)

}
val generate_verification_conditions : Shared_ast.typed Dcalc.Ast.program -> Shared_ast.ScopeName.t option -> verification_condition list

generate_verification_conditions p None will generate the verification conditions for all the variables of all the scopes of the program p, while generate_verification_conditions p (Some s) will focus only on the variables of scope s.
