Functions

func Decode

func Decode(data interface{}) (interface{}, error)

Decode decodes <data>(string/[]byte) to golang variable.

func DecodeTo

func DecodeTo(data interface{}, v interface{}) error

Decode decodes <data>(string/[]byte) to specified golang variable <v>. The <v> should be a pointer type.

func Encode

func Encode(value interface{}) ([]byte, error)

Encode encodes <value> to JSON data type of bytes.

func Valid

func Valid(data interface{}) bool

Types

type Json

type Json struct {
	// contains filtered or unexported fields
}

The customized JSON struct.

func DecodeToJson

func DecodeToJson(data interface{}, safe ...bool) (*Json, error)

DecodeToJson codes <data>(string/[]byte) to a Json object.

func Load

func Load(path string, safe ...bool) (*Json, error)
