Agda-2.2.8: A dependently typed functional programming language and proof assistant
data EitherOrBoth a b Source
unionWithM :: (Ord k, Functor m, Monad m) => (a -> a -> m a) -> Map k a -> Map k a -> m (Map k a)Source
Not very efficient (goes via a list), but it'll do.
insertWithKeyM :: (Ord k, Monad m) => (k -> a -> a -> m a) -> k -> a -> Map k a -> m (Map k a)Source
filterKeys :: Ord k => (k -> Bool) -> Map k a -> Map k aSource
Filter a map based on the keys.
