  1. adjustMinWithKey :: (k -> a -> a) -> MinPQueue k a -> MinPQueue k a

    pqueue Data.PQueue.Prio.Min

    Alter the value at the minimum key. If the queue is empty, does nothing.

  2. adjustMinWithKeyA :: Applicative f => (k -> a -> f a) -> MinPQueue k a -> f (MinPQueue k a)

    pqueue Data.PQueue.Prio.Min

    per operation. Alter the value at the minimum key in an Applicative context. If the queue is empty, does nothing.

  3. adjustNested :: (Ord k, Foldable t, IsList (t a)) => (t a -> t a) -> k -> Map k (t a) -> Map k (t a)

    skeletest Skeletest.Internal.Utils.Map

    Same as adjust, except defaulting to an empty structure if it doesn't exist, and deleting the key if the adjusted value is empty.

  4. makeJustPattern :: Name -> Pat

    dbus DBus.Generation

    No documentation available.

  5. catchJust :: forall e b (es :: [Effect]) a . Exception e => (e -> Maybe b) -> Eff es a -> (b -> Eff es a) -> Eff es a

    effectful-core Effectful.Exception

    Lifted catchJust.

  6. handleJust :: forall e b (es :: [Effect]) a . (HasCallStack, Exception e) => (e -> Maybe b) -> (b -> Eff es a) -> Eff es a -> Eff es a

    effectful-core Effectful.Exception

    Flipped version of catchJust.

  7. tryJust :: forall e b (es :: [Effect]) a . Exception e => (e -> Maybe b) -> Eff es a -> Eff es (Either b a)

    effectful-core Effectful.Exception

    Lifted tryJust.

  8. showJustName :: Name -> String

    express Data.Express.Utils.TH

    Encodes a Name as a String. This is useful when generating error messages. 

    > showJustName ''Int
"Int"

    > showJustName ''String
"String"

    > showJustName ''Maybe
"Maybe"

  9. isJust :: Maybe a -> Bool

    foundation Foundation

    The isJust function returns True iff its argument is of the form Just _.

    Examples

    Basic usage: 
    >>> isJust (Just 3)
True

    >>> isJust (Just ())
True

    >>> isJust Nothing
False
    Only the outer constructor is taken into consideration: 
    >>> isJust (Just Nothing)
True

  10. TextAttributeJustification :: TextAttribute

    gi-atk GI.Atk.Enums

    The justification of the text, if set. Values are "left", "right", "center" or "fill"
