It is necessary to add some data to the empty structure, I tried different options, but it did not help. Data is added successfully if the structure contains a simple array. I’m new to Golang. Sample code below

package main
import "fmt"
type Data struct {
    Arr []struct {
        Key1 string
        Key2 string
    }
}
func main() {
    var data Data
    fmt.Println(data)
}

I tried to add it through append, I tried it through for. I expected that the structure contained the following set
{“Arr”:[{“Key1″:”value1″,”Key2″:”value2”}]}
