  1. toPersistValueEnum :: Enum a => a -> PersistValue

    persistent Database.Persist.Class.PersistEntity

    Convenience function for getting a free PersistField instance from a type with an Enum instance. The function derivePersistField from the persistent-template package should generally be preferred. However, if you want to ensure that an ORDER BY clause that uses your field will order rows by the data constructor order, this is a better choice. Example usage in combination with fromPersistValueEnum: 

    data SeverityLevel = Low | Medium | Critical | High
deriving (Enum, Bounded)
instance PersistField SeverityLevel where
fromPersistValue = fromPersistValueEnum
toPersistValue = toPersistValueEnum

  2. SqlNumeric :: Word32 -> Word32 -> SqlType

    persistent Database.Persist.Types

    No documentation available.

  3. COptONumber :: String -> WarnLang -> CheckExplanation

    Cabal Distribution.PackageDescription.Check

    No documentation available.

  4. choiceOptFromEnum :: (Bounded b, Enum b, Show b, Eq b) => MkOptDescr (a -> b) (b -> a -> a) a

    Cabal Distribution.Simple.Command

    create a Choice option out of an enumeration type. As long flags, the Show output is used. As short flags, the first character which does not conflict with a previous one is used.

  5. ghcOptNumJobs :: GhcOptions -> Flag ParStrat

    Cabal Distribution.Simple.Program.GHC

    Run N jobs simultaneously (if possible).

  6. buildNumJobs :: BuildFlags -> Flag (Maybe Int)

    Cabal Distribution.Simple.Setup

    No documentation available.

  7. globalNumericVersion :: GlobalFlags -> Flag Bool

    Cabal Distribution.Simple.Setup

    No documentation available.

  8. dateToSnapshotNumber :: UTCTime -> Int

    Cabal Distribution.Simple.SrcDist

    Given a date produce a corresponding integer representation. For example given a date 18032008 produce the number 20080318.

  9. OptionEnum :: [String] -> OptionType

    Cabal Distribution.TestSuite

    No documentation available.

  10. OptionNumber :: Bool -> (Maybe String, Maybe String) -> OptionType
