Not able to figure out how to convert interface{} returned from function into an array of structs
As part of some practise i was trying to create a function which can take 2 slices of some type and concatenates both and returns the slice.
The code can be found here - https://play.golang.org/p/P9pfrf_qTS1
type mystruct struct {
name string
value string
}
func appendarr(array1 interface{}, array2 interface{}) interface{} {
p := reflect.ValueOf(array1)
q := reflect.ValueOf(array2)
r := reflect.AppendSlice(p, q)
return reflect.ValueOf(r).Interface()
}
func main() {
fmt.Println("=======")
array1 := []mystruct{
mystruct{"a1n1", "a1v1"},
mystruct{"a1n2", "a1v2"},
}
array2 := []mystruct{
mystruct{"a2n1", "a2v1"},
mystruct{"a2n2", "a2v2"},
}
arrayOp := appendarr(array1, array2)
fmt.Printf("arr: %#v
", arrayOp) // this shows all the elements from array1 and 2
val := reflect.ValueOf(arrayOp)
fmt.Println(val) // output is <[]main.mystruct Value>
fmt.Println(val.Interface().([]mystruct)) // exception - interface {} is reflect.Value, not []main.mystruct
}
I may have slices of different types of structs. I want to concatenate them and access the elements individually. If there is any other way of achieving the same, please do let me know.
