validateEach

Adds the v validators to elements of the schema, when the annotated class or field is a collection or Option. The type of the validator must match exactly the type of the collection's elements. This is not checked at compile-time, and might cause run-time exceptions. E.g. to validate that when an Option[Int] is defined, the value is smaller than 5, you should use:

case class Payload(
 @validateEach(Validator.max(4, exclusive = true))
 aField: Option[Int]
)
