  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. class SqlJustable a b | b -> a

    beam-core Database.Beam.Query

    Type class for things that can be nullable. This includes 'QExpr (Maybe a)', 'tbl (Nullable QExpr)', and 'PrimaryKey tbl (Nullable QExpr)'

  5. isJust_ :: SqlDeconstructMaybe be a nonNullA s => a -> QGenExpr ctxt be s Bool

    beam-core Database.Beam.Query

    Returns a QExpr that evaluates to true when the first argument is not null

  6. makeJustPattern :: Name -> Pat

    dbus DBus.Generation

    No documentation available.

  7. 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.

  8. 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.

  9. 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.

  10. 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"
