Reflex.Patch.Map

Patches on Map that consist only of insertions (including overwrites) and deletions

Documentation

newtype PatchMap k v

A set of changes to a Map. Any element may be inserted/updated or deleted. Insertions are represented as values wrapped in Just, while deletions are represented as Nothings

Constructors

PatchMap

Fields

• unPatchMap :: Map k (Maybe v)

Instances

Functor (PatchMap k)

fmapping a PatchMap will alter all of the values it will insert. Deletions are unaffected.

Methods

fmap :: (a -> b) -> PatchMap k a -> PatchMap k b

(<$) :: a -> PatchMap k b -> PatchMap k a

(Eq k, Eq v) => Eq (PatchMap k v)

Methods

(==) :: PatchMap k v -> PatchMap k v -> Bool

(/=) :: PatchMap k v -> PatchMap k v -> Bool

(Ord k, Ord v) => Ord (PatchMap k v)

Methods

compare :: PatchMap k v -> PatchMap k v -> Ordering

(<) :: PatchMap k v -> PatchMap k v -> Bool

(<=) :: PatchMap k v -> PatchMap k v -> Bool

(>) :: PatchMap k v -> PatchMap k v -> Bool

(>=) :: PatchMap k v -> PatchMap k v -> Bool

max :: PatchMap k v -> PatchMap k v -> PatchMap k v

min :: PatchMap k v -> PatchMap k v -> PatchMap k v

(Ord k, Read k, Read v) => Read (PatchMap k v)

Methods

readsPrec :: Int -> ReadS (PatchMap k v)

readList :: ReadS [PatchMap k v]

readPrec :: ReadPrec (PatchMap k v)

readListPrec :: ReadPrec [PatchMap k v]

(Show k, Show v) => Show (PatchMap k v)

Defined in Reflex.Patch.Map

Methods

showsPrec :: Int -> PatchMap k v -> ShowS

show :: PatchMap k v -> String

showList :: [PatchMap k v] -> ShowS

Ord k => Semigroup (PatchMap k v)

a <> b will apply the changes of b and then apply the changes of a. If the same key is modified by both patches, the one on the left will take precedence.

sconcat :: NonEmpty (PatchMap k v) -> PatchMap k v

stimes :: Integral b => b -> PatchMap k v -> PatchMap k v

Ord k => Monoid (PatchMap k v)

The empty PatchMap contains no insertions or deletions

Methods

mempty :: PatchMap k v

mappend :: PatchMap k v -> PatchMap k v -> PatchMap k v

mconcat :: [PatchMap k v] -> PatchMap k v

Ord k => Patch (PatchMap k v)

Apply the insertions or deletions to a given Map.
