ArgonautValueEnum

Base trait for Value-based Enumeratum Enums that automatically adds Argonaut Json Encoders and Decoders.

Example

scala> import enumeratum.values._
scala> import argonaut._
scala> import Argonaut._

scala> sealed abstract class TrafficLight(val value: Int) extends IntEnumEntry
scala> case object TrafficLight
     |     extends IntEnum[TrafficLight]
     |       with IntArgonautEnum[TrafficLight] {
     |   case object Red    extends TrafficLight(1)
     |   case object Yellow extends TrafficLight(2)
     |   case object Green  extends TrafficLight(3)
     |   val values = findValues
     | }

scala> val light: TrafficLight = TrafficLight.Red
scala> light.asJson
res0: Json = 1

scala> Json.jNumber(1).as[TrafficLight]
res1: DecodeResult[TrafficLight] = DecodeResult(Right(Red))

scala> Json.jNumber(5).as[TrafficLight]
res1: DecodeResult[TrafficLight] = DecodeResult(Left((5 is not a member of enum TrafficLight,CursorHistory(List()))))
