Exact lookup

1. 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
   

2. 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)
   

3. measNumGcs :: Measured -> !Int64

   criterion	Criterion.Types

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

4. reportNumber :: Report -> Int

   criterion	Criterion.Types

   A simple index indicating that this is the nth report.

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

   array	Data.Array.Base

   Returns the number of elements in the array.

6. tagToEnum# :: Int# -> a

   ghc-prim	GHC.Prim

   No documentation available.

7. 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.

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

   lens	Control.Lens.Iso

   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.

9. _NumTyLit :: Prism' TyLit Integer

   lens	Language.Haskell.TH.Lens

   No documentation available.

10. AI_NUMERICHOST :: AddrInfoFlag

    network	Network.Socket

    The HostName argument must be a numeric address in string form, and network name lookups will not be attempted.
