假设我必须实现在两个不同的包中声明的两个不同的接口(在两个不同的独立项目中)。
我在包裹里 A
package A
type interface Doer {
Do() string
}
func FuncA(Doer doer) {
// Do some logic here using doer.Do() result
// The Doer interface that doer should implement,
// is the A.Doer
}
并在包 B
package B
type interface Doer {
Do() string
}
function FuncB(Doer doer) {
// some logic using doer.Do() result
// The Doer interface that doer should implement,
// is the B.Doer
}
在我的main包裹里
package main
import (
"path/to/A"
"path/to/B"
)
type C int
// this method implement both A.Doer and B.Doer but
// the implementation of Do here is the one required by A !
func (c C) Do() string {
return "C now Imppement both A and B"
}
func main() {
c := C(0)
A.FuncA(c)
B.FuncB(c) // the logic implemented by C.Do method will causes a bug here !
}
如何处理这种情况?
