Enums

To create an enum you need to create a new type of type string which implements the groot.EnumType interface where the Values method should return all the values of the enum.

type EnumType interface {    Values() []string}

To define an enum UserType with values ADMIN and USER, we can use the below code:

type UserType string
const (    UserTypeAdmin UserType = "ADMIN"    UserTypeUser  UserType = "USER")
func (u UserType) Values() []string {    return []string{string(UserTypeAdmin), string(UserTypeUser)}}

You can then use UserType as a regluar type on any field.

Note, if you don't implement the EnumType interface, Groot will treat it as a regular string instead of an enum.
