从golang SDK获取GetDesignDocuments

I would like to retrieve all Design Documents of given bucket. So I prepared short code

err := cbSrc.Connect()
if err != nil {
    log.Println(err.Error())
    os.Exit(2)
}

bm := cbSrc.Bucket.Manager(username, password)

dds, err := bm.GetDesignDocuments()
if err != nil {
    log.Println(err.Error())
    os.Exit(3)
}

log.Printf("%#v
", dds)

for ind := range dds {
    fmt.Println(dds[ind].Name)
}

and I'm always receiving slice of pointers with correct length, but the addresses of the pointers is always the same

[]*gocb.DesignDocument{(*gocb.DesignDocument)(0xc82011eb50), (*gocb.DesignDocument)(0xc82011eb50), (*gocb.DesignDocument)(0xc82011eb50)}

So basically, I receive 3 times the third design model. And for range statement gives me 3 times the same value
