語法易錯(cuò)點(diǎn)
- 傳結(jié)構(gòu)的值時(shí)，結(jié)構(gòu)體的對(duì)象類型會(huì)被轉(zhuǎn)換為接收者定義的類型
dataList := []struct {
dst interface{}
src interface{}
want interface{}
}{
//{PersonM{Name: "Alice", Age: 20}, PersonM{Age: 20, Name: "Alice"}, PersonM{Name: "Alice", Age: 20}},
//{PersonM{Name: "Alice", Age: 20}, PersonM{Name: "Bob", Age: 20}, PersonM{Name: "Bob", Age: 20}},
{&PersonM{Name: "Alice", Age: 20}, PersonM{Name: "Bob", Age: 21}, PersonM{Name: "Bob", Age: 21}},
//{WomanM{Name: "Alice", Age: 20}, PersonM{Name: "Alice", Age: 20}, WomanM{Name: "Alice", Age: 20}},
//{WomanM{Name: "Alice", Age: 20}, PersonM{Name: "Alice", Age: 20, Height: 170}, WomanM{Name: "Alice", Age: 20}},
//{PersonM{Name: "Alice", Age: 20, Height: 170}, WomanM{Name: "Alice", Age: 21}, PersonM{Name: "Alice", Age: 21, Height: 170}},
//{PersonM{Name: "Alice"}, WomanM{Name: "Bob", Age: 21}, PersonM{Name: "Bob", Age: 21}},
}
- 值在使用時(shí)要初始化，不然會(huì)報(bào)訪問nil對(duì)象
runtime error: invalid memory address or nil pointer dereference\ngoroutine
