Types

type Codec

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

func New

func New(code []byte, id string) (*Codec, error)

func NewWithoutCode

func NewWithoutCode(id string) (*Codec, error)

NewWithoutCode creates encoder/decoder without any file creation but it check user script existence under /tmp/codec-id.py

func (*Codec) Decode

func (c *Codec) Decode(ctx context.Context, r []byte) (interface{}, error)

Decode sends base64 coded data into stdin of user codec script and reads string represntation of json data object from its stdout

func (*Codec) Encode

func (c *Codec) Encode(ctx context.Context, p interface{}) ([]byte, error)

Encode sends string represntation of json data object into stdin of user codec script and reads base64 coded data from its stdout
