First of all, thanks a lot for your solution andrey!
Let me explain what I'm trying to do --- I'm trying to covert my struct
into map with github.com/fatih/structs
https://groups.google.com/d/msg/golang-nuts/eyYnelZF1zo/Z0IPBcArCwAJ
but the following gave me "panic: not struct"
type Server struct {
Name string
ID int32
Enabled bool
}
s := []Server{
{
Name: "Arslan",
ID: 123456,
Enabled: true,
},
{
Name: "Arslan",
ID: 123456,
Enabled: true,
},
}
m := structs.Map(s)
That's why I'm wrapping a slice under a struct to make it works *for my
"map[string]interface {}" data*.
