Functions ¶

func ContentTypeFormat ¶ added in v1.2.0

func ContentTypeFormat(c string) string

func Decode ¶

func Decode(r io.Reader, i any, t any) error

func Encode ¶

func Encode(w io.Writer, i any, t any) error

func Marshal ¶

func Marshal(i any, t any) ([]byte, error)

func Register ¶

func Register(t string, handle Binder) error

Register 注册 Binder。约定仅在启动阶段单线程调用,参见 binderMap 注释。

func SetMimeType ¶ added in v1.2.0

func SetMimeType(id uint8, name string, typ string)

func Unmarshal ¶

func Unmarshal(b []byte, i any, t any) error

Types ¶

type Binder ¶

type Binder interface {
	Id() uint8                   // 1
	Name() string                //JSON
	String() string              //application/json
	Encode(io.Writer, any) error //同Marshal
	Decode(io.Reader, any) error //同Unmarshal
	Marshal(any) ([]byte, error)
	Unmarshal([]byte, any) error
}

var Default Binder = Json

func Get ¶ added in v1.1.0

func Get(i any) (h Binder)

Get 获取 string(name/type) uint8(id)

func GetBinder ¶ added in v1.6.9

func GetBinder(meta map[string]string, contentType ...string) (b Binder)

func New ¶

func New(t string) (b Binder)

type T ¶ added in v1.2.0

type T struct {
	Id   uint8
	Name string
	Type string
}

func Type ¶ added in v1.2.0

func Type(i any) (r *T)

Type 按 string(MIME 或 Name) / uint8(Id) 检索注册的 MIME 元数据。注意:每次调用都做 map 查表。bindings 的 Id()/Name() 内部会调用本函数, 高频路径如 binder.Json.Id() 每次产生一次 map 查找。如果成为瓶颈, 调用方可把结果缓存到本地变量复用。
