1. coarbitraryEnum :: Enum a => a -> Gen b -> Gen b

   tasty-quickcheck	Test.Tasty.QuickCheck

   A coarbitrary implementation for enums.

2. functionBoundedEnum :: (Eq a, Bounded a, Enum a) => (a -> b) -> a :-> b

   tasty-quickcheck	Test.Tasty.QuickCheck

   Provides a Function instance for types with Bounded and Enum. Use only for small types (i.e. not integers): creates the list [minBound..maxBound]!

3. shrinkBoundedEnum :: (Bounded a, Enum a, Eq a) => a -> [a]

   tasty-quickcheck	Test.Tasty.QuickCheck

   Shrink an element of a bounded enumeration.

   Example

   data MyEnum = E0 | E1 | E2 | E3 | E4 | E5 | E6 | E7 | E8 | E9
   deriving (Bounded, Enum, Eq, Ord, Show)
   

   >>> shrinkBoundedEnum E9
   [E0,E5,E7,E8]
   

   >>> shrinkBoundedEnum E5
   [E0,E3,E4]
   

   >>> shrinkBoundedEnum E0
   []
   

4. uniformEnumM :: (Enum a, Bounded a, StatefulGen g m) => g -> m a

   random	System.Random.Stateful

   Generates uniformly distributed Enum. One can use it to define a Uniform instance:

   data Colors = Red | Green | Blue deriving (Enum, Bounded)
   instance Uniform Colors where uniformM = uniformEnumM
   

5. uniformEnumRM :: (Enum a, StatefulGen g m) => (a, a) -> g -> m a

   random	System.Random.Stateful

   Generates uniformly distributed Enum in the given range. One can use it to define a UniformRange instance:

   data Colors = Red | Green | Blue deriving (Enum)
   instance UniformRange Colors where
   uniformRM = uniformEnumRM
   inInRange (lo, hi) x = isInRange (fromEnum lo, fromEnum hi) (fromEnum x)
   

6. measNumGcs :: Measured -> !Int64

   criterion	Criterion.Types

   (GC) Number of garbage collections performed. Access using fromInt.

7. reportNumber :: Report -> Int

   criterion	Criterion.Types

   A simple index indicating that this is the nth report.

8. getNumElements :: (MArray a e m, Ix i) => a i e -> m Int

   array	Data.Array.Base

   Returns the number of elements in the array.

9. tagToEnum# :: Int# -> a

   ghc-prim	GHC.Prim

   No documentation available.

10. enum :: Enum a => Iso' Int a

    lens	Control.Lens.Combinators

    This isomorphism can be used to convert to or from an instance of Enum.

    >>> LT^.from enum
    0
    

    >>> 97^.enum :: Char
    'a'
    

    Note: this is only an isomorphism from the numeric range actually used and it is a bit of a pleasant fiction, since there are questionable Enum instances for Double, and Float that exist solely for [1.0 .. 4.0] sugar and the instances for those and Integer don't cover all values in their range.
