CustomValidator
is a function validator which is converted to type CallableValidator
when passed as Scheme(CustomValidator)
.. If you need to validate for this kind of cases, you can directly use CallableValidator
with fail_flag
set to custom indicator value.
class FailureIndicator(object): pass
failure = FailureIndicator()
def CustomValidator(value):
if value == False or value in range(100):
return value
else:
return failure
# then validate as
Scheme(pyschemes.CallableValidator(CustomValidator, fail_flag=failure)).validate(False)
# Output: False
Now, the validation will fail if and only if CustomValidator
function returns value failure
. False values like False
, empty iterables etc. will be validated without error.
