# Construction

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.

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

Left-biased union of two maps. The resulting map will contain the union of the keys of the two arguments. When a key is contained in both maps the value from the first map will be preserved.

# Query

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

`findWithDefault d k m`

returns the value bound to `k`

in the map `m`

, or `d`

if `k`

is not bound in the map.

# Conversion

elems :: MapF k a -> [Some a] Source #

Return all elements of the map in the ascending order of their keys.

toAscList :: MapF k a -> [Pair k a] Source #

Return list of key-values pairs in map in ascending order.

toDescList :: MapF k a -> [Pair k a] Source #

Return list of key-values pairs in map in descending order.

=> (forall tp. a tp -> m (v tp)) | Function for evaluating a register value. |

-> t (Some a) | Set of X86 registers |

-> m (MapF a v) |

:: forall (t :: Type -> Type) (a :: k -> Type) (v :: k -> Type). (Monad m, Foldable t, OrdF a) | |

=> (forall tp. a tp -> m (v tp)) | Function for evaluating an input value to store the result in the map. |

-> t (Some a) | Set of input values (traversed via folding) |

-> m (MapF a v) |

Generate a map from a foldable collection of keys and a monadic function from keys to values.

# Filter

filter :: (forall tp. f tp -> Bool) -> MapF k f -> MapF k f Source #

Return entries with values that satisfy a predicate.

filterWithKey :: (forall tp. k tp -> f tp -> Bool) -> MapF k f -> MapF k f Source #

Return key-value pairs that satisfy a predicate.

filterGt :: OrdF k => k tp -> MapF k v -> MapF k v Source #

`filterGt k m`

returns submap of `m`

that only contains entries
that are larger than `k`

.

filterLt :: OrdF k => k tp -> MapF k v -> MapF k v Source #

`filterLt k m`

returns submap of `m`

that only contains entries
that are smaller than `k`

.

# Complex interface.

data UpdateRequest v Source #

modified by an operation.

-> MapF k a | Map to update |

-> 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.
