trait MessagesActionBuilder extends ActionBuilder[MessagesRequest, AnyContent]

This trait is an ActionBuilder that provides a MessagesRequest to the block:

class MyController @Inject()(
  messagesAction: MessagesActionBuilder,
  cc: ControllerComponents
) extends AbstractController(cc) {
  def index = messagesAction { implicit request: MessagesRequest[AnyContent] =>
     Ok(views.html.formTemplate(form)) // twirl template with form builders
  }
}

This is useful when you don't want to have to add play.api.i18n.I18nSupport to a controller for form processing.
