class transientDefault extends Annotation with StaticAnnotation

If some case class field has default value, you can use this annotation on this field to instruct an automatically derived GenCodec to not persist the value of that field if it's equal to the default value.

For example:

case class Something(str: String, @transientDefault int: Int = 42)
object Something {
  implicit val codec = GenCodec.auto[Something]
}

GenCodec.write(someOutput, Something("lol", 10)) would yield object {"str": "lol", "int": 10} but GenCodec.write(someOutput, Something("lol", 42)) would yield object {"str": "lol"} because the value of int is the same as the default value.
