1. buildEnumText :: EnumText e => e -> Builder

   columnar	Text.Columnar

   Sames as renderEnumText, but generating a Builder.

2. configEnumText :: EnumText e => e -> EnumTextConfig

   columnar	Text.Columnar

   Configures the textual representation of e generated by renderEnumText.

3. defaultEnumTextConfig :: EnumTextConfig

   columnar	Text.Columnar

   The default configEnumText for EnumText:

   • _etc_text_prep removes the prefix up to and including the first underscore ('_')
   • _etc_char_prep flips the underscores (_) to dashes (-)

4. fromFieldEnumText_ :: (EnumText e, MonadFail m) => ByteString -> m e

   columnar	Text.Columnar

   A cassava field parser using the renderEnumText format.

5. hashWithSaltEnumText :: EnumText e => Int -> e -> Int

   columnar	Text.Columnar

   For hashing e with the renderEnumText representation.

6. parseEnumText :: EnumText e => Text -> Possibly e

   columnar	Text.Columnar

   Parses an e according to the renderEnumText render.

7. renderEnumText :: EnumText e => e -> Text

   columnar	Text.Columnar

   Generate the standard textual representation according to configEnumText by default.

8. toFieldEnumText :: EnumText e => e -> ByteString

   columnar	Text.Columnar

   A cassava field encoder, using 'the renderEnumText' format.

9. class Enum a

   constrained-categories	Control.Category.Constrained.Prelude

   Class Enum defines operations on sequentially ordered types. The enumFrom... methods are used in Haskell's translation of arithmetic sequences. Instances of Enum may be derived for any enumeration type (types whose constructors have no fields). The nullary constructors are assumed to be numbered left-to-right by fromEnum from 0 through n-1. See Chapter 10 of the Haskell Report for more details. For any type that is an instance of class Bounded as well as Enum, the following should hold:

   • The calls succ maxBound and pred minBound should result in a runtime error.
   • fromEnum and toEnum should give a runtime error if the result value is not representable in the result type. For example, toEnum 7 :: Bool is an error.
   • enumFrom and enumFromThen should be defined with an implicit bound, thus:

   enumFrom     x   = enumFromTo     x maxBound
   enumFromThen x y = enumFromThenTo x y bound
   where
   bound | fromEnum y >= fromEnum x = maxBound
   | otherwise                = minBound
   

10. enumFrom :: Enum a => a -> [a]

    constrained-categories	Control.Category.Constrained.Prelude

    Used in Haskell's translation of [n..] with [n..] = enumFrom n, a possible implementation being enumFrom n = n : enumFrom (succ n).

    Examples

    • enumFrom 4 :: [Integer] = [4,5,6,7,...]

    • enumFrom 6 :: [Int] = [6,7,8,9,...,maxBound ::
      Int]
