[BigQuery] Fetching results into a Go struct

[invisible]

I am trying to fetch a string result into a Go struct. I am following the instructions  mentioned here under `Example (struct)`: https://pkg.go.dev/cloud.google.com/go/bigquery#RowIterator.Next

Following is the simplified repro of what I am trying to do.

type results struct {
	stack string
}

func read(ctx context.Context, client *bigquery.Client) error {
	query := `
	SELECT 
	stack as stack
	FROM tab1
	limit 3;`

	q := client.Query(query)
	it, err := q.Read(ctx)
	if err != nil {
		fmt.Printf("%v", err)
		return err
	}

	for {
		var row results

		err := it.Next(&row)
		if err == iterator.Done {
			break
		}
		if err != nil {
			return err
		}
		fmt.Printf("stack: %v", row.stack)
	}
	return nil
}

I can put a breakpoint and see that results are fetched correctly from the table but aren't getting assigned to the struct field as they should be. I am not sure if the example in that link is incorrect or if I am making some silly mistake. Can someone please help?

Thank you

It was a silly mistake after all. The struct field name was not exported, i.e. did not begin with a capital letter. Following is the correct way.

type results struct {
    Stack string
}
