5847 :: how can I use enum for collection of types

• Miri (orginal) [2020-01-23T18:27:14+01:00] view original

  I have a field in an object which I would like to be of the type which is one of a pre-existing enum

  type foo = enum int, bool
  
  type bar = object
      a: seq or foo
  Run

  however this results in a type mismatch. How can I extract the data from the enum like i'd like?

  Is there a spread operator like in JS?

  type Foo = int | bool
  
  assert Foo(42) is Foo
  assert Foo(true) is Foo
  Run

  Variant Type is probably what you are looking for.
