Types

type Codec

type Codec[T any] struct{}

Codec is a Codec[T] backed by encoding/json. It is safe for concurrent use.

Example
type Data struct {
	Name string
}

c := json.NewCodec[Data]()

encoded, err := c.Encode(Data{Name: "example-123"})
if err != nil {
	fmt.Printf("Encode failed: %v\n", err)
	return
}

fmt.Printf("Encoded: %s\n", string(encoded))

var decoded Data
if err := c.Decode(encoded, &decoded); err != nil {
	fmt.Printf("Decode failed: %v\n", err)
	return
}

fmt.Printf("Decoded Name: %s\n", decoded.Name)
Output:
Encoded: {"Name":"example-123"}
Decoded Name: example-123

func NewCodec

func NewCodec[T any]() Codec[T]

NewCodec returns a JSON serializer for T.

func (Codec[T]) Decode

func (Codec[T]) Decode(b []byte, v *T) error

func (Codec[T]) Encode

func (Codec[T]) Encode(v T) ([]byte, error)

type StreamCodec

type StreamCodec[T any] struct{}

StreamCodec is a StreamCodec[T] backed by encoding/json. It is safe for concurrent use.

Example
type Data struct {
	Name string
}

c := json.NewStreamCodec[Data]()

var buf bytes.Buffer
if err := c.Encode(&buf, Data{Name: "example-123"}); err != nil {
	fmt.Printf("Encode failed: %v\n", err)
	return
}

var decoded Data
if err := c.Decode(&buf, &decoded); err != nil {
	fmt.Printf("Decode failed: %v\n", err)
	return
}

fmt.Printf("Decoded Name: %s\n", decoded.Name)
Output:
Decoded Name: example-123

func NewStreamCodec

func NewStreamCodec[T any]() *StreamCodec[T]

NewStreamCodec returns a JSON stream serializer for T.

func (StreamCodec[T]) Decode

func (StreamCodec[T]) Decode(r io.Reader, v *T) error

func (StreamCodec[T]) Encode

func (StreamCodec[T]) Encode(w io.Writer, v T) error
