Package s3 provides types to support unmarshalling generic `event *json.RawMessage` types into S3 specific event structures. Sparta-based S3 event listeners can unmarshall the RawMesssage into source-specific data. Example:

func s3EventListener(event *json.RawMessage,
                      context *sparta.LambdaContext,
                      w http.ResponseWriter,
                      logger *logrus.Logger) {
  var lambdaEvent spartaS3.Event
  err := json.Unmarshal([]byte(*event), &lambdaEvent)
  if err != nil {
    logger.Error("Failed to unmarshal event data: ", err.Error())
    http.Error(w, err.Error(), http.StatusInternalServerError)
  for _, eachRecord := range lambdaEvent.Records {
    switch eachRecord.EventName {
      case "ObjectCreated:Put": {...}
      default : {...}
