Bagaimanakah saya boleh menyahzip fail dalam Go dengan cekap dan mencegah ralat biasa?

func Unzip(src, dest string) error {
    r, err := zip.OpenReader(src)
    if err != nil {
        return err
    }
    defer r.Close()

    for _, f := range r.File {
        rc, err := f.Open()
        if err != nil {
            return err
        }
        defer rc.Close()

        path := filepath.Join(dest, f.Name)
        if f.FileInfo().IsDir() {
            os.MkdirAll(path, f.Mode())
        } else {
