mongodb - Is there a way to get slice as result of Find()?

Question

Now I'm doing:

sess := mongodb.DB("mybase").C("mycollection")
var users []struct {
    Username string `bson:"username"`
}

err = sess.Find(nil).Select(bson.M{"username": 1, "_id": 0}).All(&users)
if err != nil {
    fmt.Println(err)
}

var myUsers []string
for _, user := range users{
    myUsers = append(myUsers, user.Username)
}

Is there a more effective way to get slice with usernames from Find (or another search function) directly, without struct and range loop?
