a library to create type dynamically

how to use

// 1. define struct
type Student struct {
	Age  int
	Name string
}

// 2. add reflect type
key := AddType(new(Student))

// 3. create struct from registed key
student := Make(key)

custom registed key

var i interface{} = new(Student)

// use lowercase struct name as key
name := AddTypeWithKey(i, func(i interface{}) string {
	tpe := reflect.TypeOf(i).Elem()
	return strings.ToLower(tpe.Name())
})

student, ok := Create("student").(*Student)
