Go Enum

Go does not have enum. You can simulate using constant integer or string by defining a type. Go's way of simulating enum is similar to TypeScript.

Define Enum

Numeric

type Color int

const (  // iota is reset to 0
        Red Color = iota  // Red == 0
        Yellow
        Blue
)

Parse enum from string

Either write it by hand or use code generators. NOTE: I haven't tried any of them yet.
