Module Verification.ConditionsSource

Generates verification conditions from scope definitions

    (*

    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

    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.

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.
