1. fromPersistValueEnum :: (Enum a, Bounded a) => PersistValue -> Either Text a

   persistent	Database.Persist.Class.PersistEntity

   Convenience function for getting a free PersistField instance from a type with an Enum instance. This function also requires a Bounded instance to improve the reporting of errors. Example usage in combination with toPersistValueEnum:

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

2. 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
   

3. 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.

4. OptionEnum :: [String] -> OptionType

   Cabal	Distribution.TestSuite

   No documentation available.

5. parseBoundedEnumOf :: (Bounded a, Enum a) => (a -> Text) -> Text -> Either Text a

   http-api-data	Web.HttpApiData

   Parse values based on a precalculated mapping of their Text representation.

   >>> parseBoundedEnumOf toUrlPiece "true" :: Either Text Bool
   Right True
   

   For case insensitive parser see parseBoundedEnumOfI.

6. parseBoundedEnumOfI :: (Bounded a, Enum a) => (a -> Text) -> Text -> Either Text a

   http-api-data	Web.HttpApiData

   Case insensitive. Parse values case insensitively based on a precalculated mapping of their Text representations.

   >>> parseBoundedEnumOfI toUrlPiece "FALSE" :: Either Text Bool
   Right False
   

   For case sensitive parser see parseBoundedEnumOf.

7. lookupBoundedEnumOf :: (Bounded a, Enum a, Eq b) => (a -> b) -> b -> Maybe a

   http-api-data	Web.Internal.HttpApiData

   Lookup values based on a precalculated mapping of their representations.

8. parseBoundedEnumOf :: (Bounded a, Enum a) => (a -> Text) -> Text -> Either Text a

   http-api-data	Web.Internal.HttpApiData

   Parse values based on a precalculated mapping of their Text representation.

   >>> parseBoundedEnumOf toUrlPiece "true" :: Either Text Bool
   Right True
   

   For case insensitive parser see parseBoundedEnumOfI.

9. parseBoundedEnumOfI :: (Bounded a, Enum a) => (a -> Text) -> Text -> Either Text a

   http-api-data	Web.Internal.HttpApiData

   Case insensitive. Parse values case insensitively based on a precalculated mapping of their Text representations.

   >>> parseBoundedEnumOfI toUrlPiece "FALSE" :: Either Text Bool
   Right False
   

   For case sensitive parser see parseBoundedEnumOf.

10. MaxFileNumberExceeded :: Int -> RequestParseException

    wai-extra	Network.Wai.Parse

    No documentation available.
