Please note that you can also use the 'with' validator (Valiant::Filter::With) for simple custom filter needs. Its best to use this role when you want custom filters that is going to be shared across several classes so the effort pays off in reuse.

Your class must provide the method filter_each, which will be called once for each attribute in the validation.
