1. mapEither :: Ord k => (a -> Either b c) -> MaxPQueue k a -> (MaxPQueue k b, MaxPQueue k c)

   pqueue	Data.PQueue.Prio.Max

   Map values and separate the Left and Right results.

2. mapEitherWithKey :: Ord k => (k -> a -> Either b c) -> MaxPQueue k a -> (MaxPQueue k b, MaxPQueue k c)

   pqueue	Data.PQueue.Prio.Max

   Map values and separate the Left and Right results.

3. mapKeys :: Ord k' => (k -> k') -> MaxPQueue k a -> MaxPQueue k' a

   pqueue	Data.PQueue.Prio.Max

   Map a function over all values in the queue.

4. mapKeysMonotonic :: (k -> k') -> MaxPQueue k a -> MaxPQueue k' a

   pqueue	Data.PQueue.Prio.Max

   mapKeysMonotonic f q == mapKeys f q, but only works when f is strictly monotonic. The precondition is not checked. This function has better performance than mapKeys.

5. mapMWithKey :: (Ord k, Monad m) => (k -> a -> m b) -> MaxPQueue k a -> m (MaxPQueue k b)

   pqueue	Data.PQueue.Prio.Max

   A strictly accumulating version of traverseWithKey. This works well in IO and strict State, and is likely what you want for other "strict" monads, where ⊥ >>= pure () = ⊥.

6. mapMaybe :: Ord k => (a -> Maybe b) -> MaxPQueue k a -> MaxPQueue k b

   pqueue	Data.PQueue.Prio.Max

   Map values and collect the Just results.

7. mapMaybeWithKey :: Ord k => (k -> a -> Maybe b) -> MaxPQueue k a -> MaxPQueue k b

   pqueue	Data.PQueue.Prio.Max

   Map values and collect the Just results.

8. mapWithKey :: (k -> a -> b) -> MaxPQueue k a -> MaxPQueue k b

   pqueue	Data.PQueue.Prio.Max

   Map a function over all values in the queue.

9. mapEither :: Ord k => (a -> Either b c) -> MinPQueue k a -> (MinPQueue k b, MinPQueue k c)

   pqueue	Data.PQueue.Prio.Min

   Map values and separate the Left and Right results.

10. mapEitherWithKey :: Ord k => (k -> a -> Either b c) -> MinPQueue k a -> (MinPQueue k b, MinPQueue k c)

    pqueue	Data.PQueue.Prio.Min

    Map values and separate the Left and Right results.
