func UUID ¶ Uses

❖

func UUID(spec *Config, data []byte) ([]byte, error)

type Config ¶ Uses

❖

type Config struct {
    Spec         *map[string]interface{} `json:"spec"`
    Require      bool                    `json:"require,omitempty"`
    InPlace      bool                    `json:"inplace,omitempty"`
    KeySeparator string                  `json:"keySeparator"`
}

Config contains the options that dictate the behavior of a transform. The internal `spec` object can be an arbitrary json configuration for the transform.
