type JSONCodec[T any, U any] struct {
}

JSONCodec is a codec that uses JSON for marshaling and unmarshaling. It implements the Codec interface for encoding responses and decoding requests.

func NewJSONCodec[T any, U any]() *JSONCodec[T, U]

NewJSONCodec creates a new JSONCodec instance for the specified types. T represents the request type and U represents the response type.

func (c *JSONCodec[T, U]) Decode(r *http.Request) (T, error)

Decode decodes the request body into a value of type T. It reads the entire request body and unmarshals it from JSON.

func (c *JSONCodec[T, U]) Encode(w http.ResponseWriter, resp U) error

Encode encodes a value of type U into the response. It marshals the value to JSON and writes it to the response with the appropriate content type.

type ProtoCodec[T proto.Message, U proto.Message] struct{}

Force T to be a pointer to a type implementing proto.Message.

func NewProtoCodec[T proto.Message, U proto.Message]() *ProtoCodec[T, U]

NewProtoCodec creates a new ProtoCodec instance.

func (c *ProtoCodec[T, U]) Decode(r *http.Request) (T, error)

Decode reads the request body and unmarshals into T (which is a pointer).

func (c *ProtoCodec[T, U]) Encode(w http.ResponseWriter, resp U) error

Encode marshals U (also a pointer type) and writes to response.
