  1. divideMaybe :: C a => a -> a -> a -> Maybe a

    numeric-prelude Number.ResidueClass

    The division may be ambiguous. In this case an arbitrary quotient is returned. 

    0:4 * 2:4 == 0/:4
2:4 * 2:4 == 0/:4

  2. isCompatibleMaybe :: Eq a => Maybe a -> Maybe a -> Bool

    numeric-prelude Number.ResidueClass.Maybe

    No documentation available.

  3. matchMaybe :: Maybe a -> Maybe a -> Maybe a

    numeric-prelude Number.ResidueClass.Maybe

    No documentation available.

  4. intersectWithKeyMaybe :: OrdF k => (forall (tp :: v) . () => k tp -> a tp -> b tp -> Maybe (c tp)) -> MapF k a -> MapF k b -> MapF k c

    parameterized-utils Data.Parameterized.Map

    Applies a function to the pairwise common elements of two maps. Formally, we have that intersectWithKeyMaybe f x y contains a binding from a key k to a value v if and only if x and y bind k to x_k and y_k and f x_k y_k = Just v.

  5. mapMaybeWithKey :: (forall (tp :: v) . () => k tp -> f tp -> Maybe (g tp)) -> MapF k f -> MapF k g

    parameterized-utils Data.Parameterized.Map

    Map keys and elements and collect Just results.

  6. fromMaybeS :: a -> MaybeS a -> a

    parameterized-utils Data.Parameterized.Utils.BinTree

    No documentation available.

  7. elemAtMaybe :: forall (n :: Natural) a . Int -> Vector n a -> Maybe a

    parameterized-utils Data.Parameterized.Vector

    Get the element at the given index. O(1)

  8. insertAtMaybe :: forall a (n :: Natural) . Int -> a -> Vector n a -> Maybe (Vector n a)

    parameterized-utils Data.Parameterized.Vector

    Insert an element at the given index. Return Nothing if the element is outside the vector bounds. O(n).

  9. getUserRuleMaybe :: (ShakeValue key, Typeable a) => key -> (a -> Maybe String) -> (a -> Maybe b) -> Action (Maybe (Int, b))

    shake Development.Shake.Rule

    A version of getUserRuleList that fails if there is more than one result Requires a key for better error messages.

  10. cmdMaybe :: String -> [String] -> IO (Maybe String)

    simple-cmd SimpleCmd

    cmdMaybe c args runs a command, maybe returning output if it succeeds
