枚举作为go中变量的属性

Question

Let's say I have something like this:

const (
    FOO int = iota
    BAR
    BAZ
)

And I can access to variables by FOO, BAR and so on. But storing a big amount of constants in one namespace isn't good so I'm trying to hide this enum in structure or something like that so I can get value by typing actions.FOO in same namespace. I've tried many ways but didn't find anything like that. I would like to mention that easiest workaround, in this case, will be anonymous structure but I wanna keep auto indexing with iota.

Answer 1

The only way to assign some sort of enumerable behind the property without creating the separate package that I found is to use anonymous structure.

type someType int

var ConstantsList = struct {
   FOO, BAR, BAZ someType
}{1, 2, 3}

There are few downsides of using it, it's not immutable, and doesn't have auto increment.
