  1. genValidStructurally :: (Validity a, Generic a, GGenValid (Rep a)) => Gen a

    genvalidity Data.GenValidity

    Generate a valid value by generating all the sub parts using the Generic instance, and trying that until a valid value has been generated

    genValidStructurally = genValidStructurallyWithoutExtraChecking `suchThat` isValid
    
    This is probably the function that you are looking for. If you do use this function to override genValid, you probably also want to use shrinkValidStructurally to override shrinkValid.

  2. genValidStructurallyWithoutExtraChecking :: (Generic a, GGenValid (Rep a)) => Gen a

    genvalidity Data.GenValidity

    Generate a valid value by generating all the sub parts using the Generic instance, This generator is _not_ guaranteed to generate a valid value. This is probably _not_ the function that you are looking for when overriding genValid _unless_ the type in question has no _extra_ validity constraints on top of the validity of its sub parts.

  3. shrinkValid :: GenValid a => a -> [a]

    genvalidity Data.GenValidity

    Shrink a valid value. The default implementation is as follows:

    shrinkValid = shrinkValidStructurally
    
    It is important that this shrinking function only shrinks values to valid values. If shrinkValid ever shrinks a value to an invalid value, the test that is being shrunk for might fail for a different reason than for the reason that it originally failed. This would lead to very confusing error messages.

  4. shrinkValidStructurally :: (Validity a, Generic a, GValidRecursivelyShrink (Rep a), GValidSubterms (Rep a) a) => a -> [a]

    genvalidity Data.GenValidity

    Shrink a term to any of its immediate valid subterms, and also recursively shrink all subterms, and then filtering out the results that are not valid.

    shrinkValidStructurally = filter isValid . shrinkValidStructurallyWithoutExtraFiltering
    
    This is probably the function that you are looking for.

  5. shrinkValidStructurallyWithoutExtraFiltering :: (Generic a, GValidRecursivelyShrink (Rep a), GValidSubterms (Rep a) a) => a -> [a]

    genvalidity Data.GenValidity

    Shrink a term to any of its immediate valid subterms, and also recursively shrink all subterms. This shrinking function is _not_ guaranteed to shrink to valid values. This is probably _not_ the function that you are looking for when overriding shrinkValid _unless_ the type in question has no _extra_ validity constraints on top of the validity of its sub parts.

  6. structurallyValidSubterms :: (Generic a, GValidSubterms (Rep a) a) => a -> [a]

    genvalidity Data.GenValidity

    All immediate validSubterms of a term.

  7. cc_ann_id :: ConfiguredComponent -> AnnotatedId ComponentId

    Cabal Distribution.Backpack.ConfiguredComponent

    Unique identifier of component, plus extra useful info.

  8. cc_cid :: ConfiguredComponent -> ComponentId

    Cabal Distribution.Backpack.ConfiguredComponent

    Uniquely identifies a configured component.

  9. cc_pkgid :: ConfiguredComponent -> PackageId

    Cabal Distribution.Backpack.ConfiguredComponent

    The package this component came from.

  10. module Distribution.Backpack.DescribeUnitId
