Documentation

newtype PatchMapWithMove k (v :: Type) Source #

Patch a Map with additions, deletions, and moves. Invariant: If key k1 is coming from From_Move k2, then key k2 should be going to Just k1, and vice versa. There should never be any unpaired From/To keys.

Constructors

PatchMapWithMove'
Fields unPatchMapWithMove' :: PatchMapWithPatchingMove k (Proxy v) Extract the underlying 'PatchMapWithPatchingMove k (Proxy v)'

Bundled Patterns

pattern PatchMapWithMove :: Map k (NodeInfo k v) -> PatchMapWithMove k v

patchMapWithMove :: Ord k => Map k (NodeInfo k v) -> Maybe (PatchMapWithMove k v) Source #

Create a PatchMapWithMove, validating it

patchMapWithMoveInsertAll :: Map k v -> PatchMapWithMove k v Source #

Create a PatchMapWithMove that inserts everything in the given Map

insertMapKey :: k -> v -> PatchMapWithMove k v Source #

Make a PatchMapWithMove k v which has the effect of inserting or updating a value v to the given key k, like insert.

moveMapKey :: Ord k => k -> k -> PatchMapWithMove k v Source #

Make a PatchMapWithMove k v which has the effect of moving the value from the first key k to the second key k, equivalent to:

    delete src (maybe map (insert dst) (Map.lookup src map))

swapMapKey :: Ord k => k -> k -> PatchMapWithMove k v Source #

Make a PatchMapWithMove k v which has the effect of swapping two keys in the mapping, equivalent to:

    let aMay = Map.lookup a map
        bMay = Map.lookup b map
    in maybe id (Map.insert a) (bMay <> aMay)
     . maybe id (Map.insert b) (aMay <> bMay)
     . Map.delete a . Map.delete b $ map

deleteMapKey :: k -> PatchMapWithMove k v Source #

Make a PatchMapWithMove k v which has the effect of deleting a key in the mapping, equivalent to delete.

unsafePatchMapWithMove :: Map k (NodeInfo k v) -> PatchMapWithMove k v Source #

Wrap a Map k (NodeInfo k v) representing patch changes into a PatchMapWithMove k v, without checking any invariants.

Warning: when using this function, you must ensure that the invariants of PatchMapWithMove are preserved; they will not be checked.

patchMapWithMoveNewElements :: PatchMapWithMove k v -> [v] Source #

Returns all the new elements that will be added to the Map.

patchMapWithMoveNewElementsMap :: PatchMapWithMove k v -> Map k v Source #

Return a Map k v with all the inserts/updates from the given PatchMapWithMove k v.

patchThatSortsMapWith :: Ord k => (v -> v -> Ordering) -> Map k v -> PatchMapWithMove k v Source #

Create a PatchMapWithMove that, if applied to the given Map, will sort its values using the given ordering function. The set keys of the Map is not changed.

patchThatChangesAndSortsMapWith :: (Ord k, Ord v) => (v -> v -> Ordering) -> Map k v -> Map k v -> PatchMapWithMove k v Source #

Create a PatchMapWithMove that, if applied to the first Map provided, will produce a Map with the same values as the second Map but with the values sorted with the given ordering function.

patchThatChangesMap :: (Ord k, Ord v) => Map k v -> Map k v -> PatchMapWithMove k v Source #

Create a PatchMapWithMove that, if applied to the first Map provided, will produce the second Map.
