reflectx

make reflect type serializable, conveniently for RPC

一个可以序列化的反射类型，代替 reflect.Type，便于编写 RPC 代码

example

TypeOf gets the type

使用 TypeOf 获得类型

	tp := TypeOf(1)
	// {"kind":"int"}
	t.Log(tp.String())

    tp = TypeOf(struct {
		Name string
		Age  int64
	}{})
	// {"kind":"struct","struct":{"Age":{"kind":"int64"},"Name":{"kind":"string"}},"extra":{"field_0":"Name","field_1":"Age","fields_number":2}}
	t.Log(tp.String())

    tp = TypeOf(map[string]int{})
	// {"kind":"map","struct":{"key_type":{"kind":"string"},"value_type":{"kind":"int"}}}
	t.Log(tp.String())

    tp = TypeOf([]string{})
	// {"kind":"slice","struct":{"element_type":{"kind":"string"}}}
	t.Log(tp.String())

FromGoType converts the std reflect.Type to Type

FromGoType 可以将标准库中的 reflect.Type 转为 Type

GoType returns the std lib reflect.Type representation of the Type

GoType 将 Type 转为 标准库中的 reflect.Type

Types

type Type

type Type struct {
	Kind   string          `json:"kind,omitempty"`   // reflect.Type.Kind().String()
	Struct map[string]Type `json:"struct,omitempty"` // struct info of the type
	Extra  map[string]any  `json:"extra,omitempty"`  // extra info of the type. Such as array length
}

Type is a serializable representation of a Go type.

Field Kind is same as reflect.Type::Kind() Struct gives the complete info of the type if the Kind field cannot specify the type

func FromGoType

func FromGoType(goType reflect.Type) Type

FromGoType converts the std reflect.Type to Type

func TypeOf

func TypeOf(i any) Type

TypeOf returns the type of i

func (Type) GoType

func (t Type) GoType() reflect.Type

GoType returns the std lib reflect.Type representation of the Type

func (Type) String

func (t Type) String() string
