final case class Optional[O, F[_], I](fieldName: String, base: F[I], extract: Extract[O, Option[I]]) extends PropSchema[O, F, Option[I]] with Product with Serializable
Class describing an optional property of a record. Since in many serialized forms optional properties may be omitted entirely from the serialized form, a distinct type is needed in order to be able to correctly interpret the absence of a field.
- fieldName
The name of the property.
- base
Schema for the property's value type.
- extract
Extract lens from the record type to the property.
