Golang的引用类型

I have this

var Map = map[string]Model{}

var (
    mtx    sync.Mutex
    people Map
)

I am getting this error:

Is there any way of referencing the type of the Map, something like this:

var (
    mtx    sync.Mutex
    people reflect.Type(Map)  // <<< ?
)

or should I just resort to declare the type like so:

type Map map[string]Model

and the initializing the map like I do on line 54? I was just trying to initialize the map in the file without having to do it in the Init func.

I'm not sure I understood your problem but you can do something like this:

 var Map = map[string]Model{}

 var (
   mtx sync.Mutex
   people = Map
 )

That way people is initialized as same as Map.

You can use map literal to initialize map:

type Model struct {}

var people = map[string]Model{
    "Foo": Model{},
    "Bar":   Model{},
}

I think you want to use something like

type Model struct{}
type ModelMap map[string]Model

var (
    mtx sync.Mutex
    people = ModelMap{}
)
