Go 错误.如果它包含切片，则返回FALSE

当我的Error struct 包含嵌套在其中的片时，Errs.is似乎不能正常工作:

package main

import (
    "errors"
    "fmt"
    "os"
)

type Response struct {
    Details []string
}

type ErrResponseError struct {
    Response Response
}

func (err ErrResponseError) Error() string {
    return "response error"
}

func main() {
    err := ErrResponseError{}
    fmt.Fprintf(os.Stdout, "equal: %v", errors.Is(err, ErrResponseError{}))
}

返回

等于:FALSE

package main

import (
    "errors"
    "fmt"
    "os"
)

type Response struct {
    Details string // Changed this line
}

type ErrResponseError struct {
    Response Response
}

func (err ErrResponseError) Error() string {
    return "response error"
}

func main() {
    err := ErrResponseError{}
    fmt.Fprintf(os.Stdout, "equal: %v", errors.Is(err, ErrResponseError{}))
}

返回

等于:真
