A type for abstracting enums into a single type.

For example, your existing app might look like:

attribute :status, :atom, constraints: [one_of: [:open, :closed]]

But as that starts to spread around your system you may find that you want to centralize that logic. To do that, use this module to define an Ash type easily:

defmodule MyApp.TicketStatus do
  use Ash.Type.Enum, values: [:open, :closed]
end

Valid values are:

• The atom itself, e.g :open
• A string that matches the atom, e.g "open"
• A string that matches the atom after being downcased, e.g "OPEN" or "oPeN"
• A string that matches the stringified, downcased atom, after itself being downcased. This allows for enum values like :Open, :SomeState and :Some_State
