Consider enums in Records #223

RobertBaruch · 2019-09-21T21:40:02Z

Instead of:

class EnumItem(Enum):
  THING1 = 0
  THING2 = 1

class Bag(Layout):
  def __init__(self):
    super().__init__([
      ("thing", Signal.enum(EnumItem).shape())
    ])

Maybe:

class Bag(Layout):
  def __init__(self):
    super().__init__([
      ("thing", EnumItem)
    ])

With the understanding that fanning an element in requires the "inactive" outputs to be zero. This can inform the design of the enumerated class:

class EnumItem(Enum):
  NONE = 0
  THING1 =1
  THING2 = 2
