获取Firestore文档的值

I am trying to use Firestore as my backend to store document data. The response from Firestore to

docs, _ := q.Documents(ctx).GetAll()

is of type

var docs []*firestore.DocumentSnapshot

Assuming my document has the struture

map[array:[a b] text:bla]

How can I access the values in the *firestore.DocumentSnapshot?

I see a result when

for _, doc := range docs {
    fmt.Println(doc.Data())
}

get's executed and it prints

map[array:[a b] text:bla]

func g() {
    ctx := context.Background()
    client, _ := firestore.NewClient(ctx, "myapp")

    defer client.Close()

    q := client.Collection("my").
        Limit(10)

    docs, _ := q.Documents(ctx).GetAll()

    for _, doc := range docs {
        fmt.Println(doc.Data())
    }
}

I would like to use the values in a http template in my application in a slice of struct.
