Basically when enum members define the bitmask, and the decoded output is the superposition of the enum members.

Something like

type feature_mask =
  | FEATURE1 [@value 1]
  | FEATURE2 [@value 8]
  | FEATURE3 [@value 0x400]
  [@@deriving maskenum, show]

And show attribute will generate the "FEATURE1 | FEATURE3" for 0x401 value for example.
