codec

type Codec ¶

type Codec interface {
	Encode(w io.Writer, v any) error
	Decode(r io.Reader, v any) error
}

Codec handles serialization and deserialization for a specific media type.

func Lookup(r *http.Request, contentType string) (string, Codec)

type CodecRegistry ¶

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

CodecRegistry maps media types to Codec implementations and injects itself into the request context. It implements plugin.ContextInjector — the framework injects it on every request automatically.

func NewCodecRegistry() *CodecRegistry

func (cr *CodecRegistry) Inject(r *http.Request) *http.Request

func (cr *CodecRegistry) Register(mediaType string, c Codec)

type JsonCodec ¶

type JsonCodec struct{}

JsonCodec is the built-in Codec for application/json. Auto-registered by the framework — no setup required.

func (c *JsonCodec) Decode(r io.Reader, v any) error

func (c *JsonCodec) Encode(w io.Writer, v any) error

type MsgpackCodec ¶

type MsgpackCodec struct{}

MsgpackCodec provides application/msgpack serialization and deserialization. It implements plugin.Installer to register itself into the CodecRegistry at startup.

router.AddPlugin(&codec.MsgpackCodec{})

func (c *MsgpackCodec) Decode(r io.Reader, v any) error

func (c *MsgpackCodec) Encode(w io.Writer, v any) error

func (c *MsgpackCodec) Install(ctx plugin.PluginContext)

type TextCodec ¶

type TextCodec struct{}

TextCodec is the built-in Codec for text/plain. Auto-registered by the framework — no setup required.

func (c *TextCodec) Decode(r io.Reader, v any) error

func (c *TextCodec) Encode(w io.Writer, v any) error

type XmlCodec ¶

type XmlCodec struct{}

XmlCodec provides application/xml serialization and deserialization. It implements plugin.Installer to register itself into the CodecRegistry at startup.

router.AddPlugin(&codec.XmlCodec{})

func (c *XmlCodec) Decode(r io.Reader, v any) error

func (c *XmlCodec) Encode(w io.Writer, v any) error

func (c *XmlCodec) Install(ctx plugin.PluginContext)

type YamlCodec ¶

type YamlCodec struct{}

YamlCodec provides application/yaml serialization and deserialization. It implements plugin.Installer to register itself into the CodecRegistry at startup.

router.AddPlugin(&codec.YamlCodec{})

func (c *YamlCodec) Decode(r io.Reader, v any) error

func (c *YamlCodec) Encode(w io.Writer, v any) error

func (c *YamlCodec) Install(ctx plugin.PluginContext)
