JsonAdapter

trait JsonAdapter[T] extends JsonInput[T] with JsonOutput[T]

Consolidates JsonInput and JsonOutput.

import little.json.Implicits._

case class User(id: Int, name: String)

implicit object UserAdapter extends JsonAdapter[User] {
  // Define how to read User from JsonValue

  def writing(user: User): JsonValue =

}

// Write User to JsonValue
