目前我有這樣的類型：package hellotype object map[string]anyfunc add[T any](obj object, key string, val T) {   switch value := obj[key].(type) {   case nil:      obj[key] = val   case T:      obj[key] = []T{value, val}   case []T:      obj[key] = append(value, val)   }}我用它來(lái)存儲(chǔ)不同類型的數(shù)字。我正在考慮限制允許的類型，如下所示：package hellotype number interface {   isNumber()}type Int32 int32func (Int32) isNumber(){}type Float32 float32func (Float32) isNumber(){}type object map[string]number但我不確定如何像以前一樣實(shí)現(xiàn)我的添加功能。我嘗試了相同的功能，但我得到了這個(gè)：cannot use val (variable of type T constrained by any) as type number in assignment:   T does not implement number (missing isNumber method)所以我將簽名更改為：func add[T number](obj object, key string, val T)但我得到另一個(gè)錯(cuò)誤：cannot use []T{…} (value of type []T) as type number in assignment:   []T does not implement number (missing isNumber method)有沒(méi)有可能像我想做的那樣做？
