Construction

empty :: MapF k a Source #

Return empty map

singleton :: k tp -> a tp -> MapF k a Source #

Return map containing a single element

insert :: OrdF k => k tp -> a tp -> MapF k a -> MapF k a Source #

Insert a binding into the map, replacing the existing binding if needed.

insertWith :: OrdF k => (a tp -> a tp -> a tp) -> k tp -> a tp -> MapF k a -> MapF k a Source #

insertWith f new m inserts the binding into m.

It inserts f new old if m already contains an equivalent value old, and new otherwise. It returns an Unchanged value if the map stays the same size and an Updated value if a new entry was inserted.

Delete a value from the map if present.

union :: OrdF k => MapF k a -> MapF k a -> MapF k a Source #

lookup :: OrdF k => k tp -> MapF k a -> Maybe (a tp) Source #

Return true if key is bound in map.

notMember :: OrdF k => k tp -> MapF k a -> Bool Source #

Constructors

Keep

Keep the current value.

Set the value to a new value.

Delete

Delete a value.

data Updated a Source #

Updated a contains a value that has been flagged on whether it was modified by an operation.

Constructors

Updated !a 
Unchanged !a 

updateAtKey Source #

Arguments

:: (OrdF k, Functor f) 
=> k tp

Key to update

-> f (Maybe (a tp))

Action to call if nothing is found

-> (a tp -> f (UpdateRequest (a tp)))

Action to call if value is found.

-> f (Updated (MapF k a)) 

Log-time algorithm that allows a value at a specific key to be added, replaced, or deleted.

mergeWithKeyM :: forall k a b c m. (Applicative m, OrdF k) => (forall tp. k tp -> a tp -> b tp -> m (Maybe (c tp))) -> (MapF k a -> m (MapF k c)) -> (MapF k b -> m (MapF k c)) -> MapF k a -> MapF k b -> m (MapF k c) Source #

Merge bindings in two maps to get a third.

The first function is used to merge elements that occur under the same key in both maps. Return Just to add an entry into the resulting map under this key or Nothing to remove this key from the resulting map.

The second function will be applied to submaps of the first map argument where no keys overlap with the second map argument. The result of this function must be a map with a subset of the keys of its argument. This means the function can alter the values of its argument and it can remove key-value pairs from it, but it must not introduce new keys.

Third function is analogous to the second function except that it applies to the second map argument of mergeWithKeyM instead of the first.

Common examples of the two functions include id when constructing a union or const empty when constructing an intersection.
