úÎ¥(SafeA class of types for which Validity!-related values can be generated.If you also write  Arbitrary instances for  GenValidity( types, it may be best to simply write arbitrary = genValid.TGenerate a truly arbitrary datum, this should cover all possible values in the typePGenerate a valid datum, this should cover all possible valid values in the type)The default implementation is as follows: + genValid = genUnchecked `suchThat` isValidÆTo speed up testing, it may be a good idea to implement this yourself. If you do, make sure that it is possible to generate all possible valid data, otherwise your testing may not cover all cases.IGenerate an invalid datum, this should cover all possible invalid values 4genInvalid = genUnchecked `suchThat` (not . isValid)ÈTo speed up testing, it may be a good idea to implement this yourself. If you do, make sure that it is possible to generate all possible invalid data, otherwise your testing may not cover all cases. A version of listOf. that takes size into account more accurately.nIf we can generate values of a certain type, we can also generate lists of them. This instance ensures that genValid. generates only lists of valid data and that  genInvalid_ generates lists of data such that there is at least one value in there that does not satisfy isValid, the rest is unchecked.   *genvalidity-0.1.0.0-5j5Npj2AkRl8TjU7nQFzvKData.GenValidity GenValidity genUncheckedgenValid genInvalid genListOf$fGenValidity[]$fGenValidityMaybe'validity-0.1.0.0-CaJf8KKVjlnEeuwwWCtaFo Data.ValidityValidityisValid
