12.  trait NameAdapter extends (String) => String

    Adapter function to transform case classes member names during the derivation process

    Adapter function to transform case classes member names during the derivation process

    A NameAdapter can be used to customize the derivation process, allowing to apply a transformation function to case classes member names when deriving serializers/deserializers

    For instance, it can be used to derive serializers/deserializers that use a different casing for the json keys.

    For example, to derive a Format[A] that uses snake_case for the json keys (using the predefined NameAdapter.snakeCase)

    import julienrf.json.derived
    import julienrf.json.derived.NameAdapter
    import play.api.libs.json.{Format, Json}
    
    case class Bar(camelCase: String)
    object Bar {
      implicit val format: Format[Bar] = derived.oformat[Bar](NameAdapter.snakeCase)
    }

    scala> Json.toJson(Bar("a json value"))
    res0: play.api.libs.json.JsValue = {"camel_case":"a json value"}
    
    scala> Json.fromJson[Bar](Json.parse("""{"camel_case":"a json value"}"""))
    res1: play.api.libs.json.JsResult[Bar] = JsSuccess(Bar(a json value),)

13.  trait TypeTag[A] extends AnyRef
