JsonSerializerOptions merge(JsonSerializerOptions? options) {
  if (options == null) {
    return JsonSerializerOptions(
      types: [...types],
      converters: [...converters],
      namingConventions: [...namingConventions],
      jsonNamingConvention: jsonNamingConvention,
    );
  }

  return JsonSerializerOptions(
    types: [...types, ...options.types],
    converters: [...converters, ...options.converters],
    namingConventions: [...namingConventions, ...options.namingConventions],
    jsonNamingConvention:
        options.jsonNamingConvention ?? jsonNamingConvention,
  );
