9. 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),)
