1. queryParamMaybe :: forall a (m :: Type -> Type) . (Parsable a, Monad m) => Text -> ActionT m (Maybe a)

   scotty	Web.Scotty.Trans

   Look up a query parameter. Returns Nothing if the parameter is not found or cannot be parsed at the right type. NB : Doesn't throw exceptions, so developers must raiseStatus or throw to signal something went wrong. Since: 0.21

2. captureParamMaybe :: forall a (m :: Type -> Type) . (Parsable a, Monad m) => Text -> ActionT m (Maybe a)

   scotty	Web.Scotty.Trans.Strict

   Look up a capture parameter. Returns Nothing if the parameter is not found or cannot be parsed at the right type. NB : Doesn't throw exceptions. In particular, route pattern matching will not continue, so developers must raiseStatus or throw to signal something went wrong. Since: 0.21

3. formParamMaybe :: forall (m :: Type -> Type) a . (MonadUnliftIO m, Parsable a) => Text -> ActionT m (Maybe a)

   scotty	Web.Scotty.Trans.Strict

   Look up a form parameter. Returns Nothing if the parameter is not found or cannot be parsed at the right type. NB : Doesn't throw exceptions, so developers must raiseStatus or throw to signal something went wrong. Since: 0.21

4. queryParamMaybe :: forall a (m :: Type -> Type) . (Parsable a, Monad m) => Text -> ActionT m (Maybe a)

   scotty	Web.Scotty.Trans.Strict

   Look up a query parameter. Returns Nothing if the parameter is not found or cannot be parsed at the right type. NB : Doesn't throw exceptions, so developers must raiseStatus or throw to signal something went wrong. Since: 0.21

5. mapMaybe :: (a -> Maybe b) -> EnumMap k a -> EnumMap k b

   enummapset	Data.EnumMap.Lazy

6. mapMaybeWithKey :: Enum k => (k -> a -> Maybe b) -> EnumMap k a -> EnumMap k b

   enummapset	Data.EnumMap.Lazy

   No documentation available.

7. mapMaybe :: (a -> Maybe b) -> EnumMap k a -> EnumMap k b

   enummapset	Data.EnumMap.Strict

   No documentation available.

8. mapMaybeWithKey :: Enum k => (k -> a -> Maybe b) -> EnumMap k a -> EnumMap k b

   enummapset	Data.EnumMap.Strict

   No documentation available.

9. bitSizeMaybe :: Bits a => a -> Maybe Int

   ghc-internal	GHC.Internal.Bits

   Return the number of bits in the type of the argument. The actual value of the argument is ignored. Returns Nothing for types that do not have a fixed bitsize, like Integer.

10. bitSizeMaybe :: Bits a => a -> Maybe Int

    ghc-internal	GHC.Internal.Data.Bits

    Return the number of bits in the type of the argument. The actual value of the argument is ignored. Returns Nothing for types that do not have a fixed bitsize, like Integer.
