# Query

null :: KeyMap v -> Bool #

Is the map empty?

lookup :: Key -> KeyMap v -> Maybe v #

Return the value to which the specified key is mapped, or Nothing if this map contains no mapping for the key.

(!?) :: KeyMap v -> Key -> Maybe v #

Return the value to which the specified key is mapped, or Nothing if this map contains no mapping for the key.

This is a flipped version of `lookup`.

Since: 2.1.1.0

size :: KeyMap v -> Int #

Return the number of key-value mappings in this map.

member :: Key -> KeyMap a -> Bool #

Is the key a member of the map?

# Construction

empty :: KeyMap v #

Construct an empty map.

singleton :: Key -> v -> KeyMap v #

Construct a map with a single element.

## Insertion

insert :: Key -> v -> KeyMap v -> KeyMap v #

Associate the specified value with the specified key in this map. If this map previously contained a mapping for the key, the old value is replaced.

insertWith :: (a -> a -> a) -> Key -> a -> KeyMap a -> KeyMap a #

Insert with a function combining new and old values, taken in that order.

Since: 2.1.1.0

# Deletion

delete :: Key -> KeyMap v -> KeyMap v #

Remove the mapping for the specified key from this map if present.

# Update

alterF :: Functor f => (Maybe v -> f (Maybe v)) -> Key -> KeyMap v -> f (KeyMap v) #

`alterF` can be used to insert, delete, or update a value in a map.

# Combine

difference :: KeyMap v -> KeyMap v' -> KeyMap v #

Difference of two maps. Return elements of the first map not existing in the second.

union :: KeyMap v -> KeyMap v -> KeyMap v #

The (left-biased) union of two maps. It prefers the first map when duplicate keys are encountered, i.e. (`union` == `unionWith` `const`).

unionWith :: (v -> v -> v) -> KeyMap v -> KeyMap v -> KeyMap v #

The union with a combining function.

unionWithKey :: (Key -> v -> v -> v) -> KeyMap v -> KeyMap v -> KeyMap v #

The union with a combining function.

intersection :: KeyMap a -> KeyMap b -> KeyMap a #

The (left-biased) intersection of two maps (based on keys).

intersectionWith :: (a -> b -> c) -> KeyMap a -> KeyMap b -> KeyMap c #

The intersection with a combining function.

intersectionWithKey :: (Key -> a -> b -> c) -> KeyMap a -> KeyMap b -> KeyMap c #

The intersection with a combining function.

alignWith :: (These a b -> c) -> KeyMap a -> KeyMap b -> KeyMap c #

Generalized union with combining function.

alignWithKey :: (Key -> These a b -> c) -> KeyMap a -> KeyMap b -> KeyMap c #

Generalized union with combining function.

# Lists

fromList :: [(Key, v)] -> KeyMap v #

Construct a map with the supplied mappings. If the list contains duplicate mappings, the later mappings take precedence.

    >>> fromList [("a", 'x'), ("a", 'y')]
    fromList [("a",'y')]

fromListWith :: (v -> v -> v) -> [(Key, v)] -> KeyMap v #

Construct a map from a list of elements. Uses the provided function, f, to merge duplicate entries with (f newVal oldVal).

toList :: KeyMap v -> [(Key, v)] #

Return a list of this map's keys and elements.

The order is not stable. Use `toAscList` for stable ordering.

toAscList :: KeyMap v -> [(Key, v)] #

Return a list of this map's elements in ascending order based of the textual key.

elems :: KeyMap v -> [v] #

Return a list of this map' elements.

Since: 2.0.3.0

Transform the keys and values of a `KeyMap`.

traverse :: Applicative f => (v1 -> f v2) -> KeyMap v1 -> f (KeyMap v2) #

traverseWithKey :: Applicative f => (Key -> v1 -> f v2) -> KeyMap v1 -> f (KeyMap v2) #

Perform an Applicative action for each key-value pair in a `KeyMap` and produce a `KeyMap` of all the results.
