Data.HashMap.Strict.InsOrd

Description

InsOrdHashMap is like HashMap, but it folds and traverses in insertion order.

This module interface mimics Data.HashMap.Strict, with some additions.

Synopsis

Documentation

data InsOrdHashMap k v Source #

HashMap which tries its best to remember insertion order of elements.

Arguments

=> v

Default value to return.

-> k 
-> InsOrdHashMap k v 
-> v 

insert :: (Eq k, Hashable k) => k -> v -> InsOrdHashMap k v -> InsOrdHashMap k v Source #

insertWith :: (Eq k, Hashable k) => (v -> v -> v) -> k -> v -> InsOrdHashMap k v -> InsOrdHashMap k v Source #

Combine

unionWith :: (Eq k, Hashable k) => (v -> v -> v) -> InsOrdHashMap k v -> InsOrdHashMap k v -> InsOrdHashMap k v Source #

The union of two maps. If a key occurs in both maps, the provided function (first argument) will be used to compute the result.

Ordered traversal will go thru keys in the first map first.

unionWithKey :: (Eq k, Hashable k) => (k -> v -> v -> v) -> InsOrdHashMap k v -> InsOrdHashMap k v -> InsOrdHashMap k v Source #

unions :: (Eq k, Hashable k, Foldable f) => f (InsOrdHashMap k v) -> InsOrdHashMap k v Source #

Transformations

map :: (v1 -> v2) -> InsOrdHashMap k v1 -> InsOrdHashMap k v2 Source #

mapKeys :: (Eq k', Hashable k') => (k -> k') -> InsOrdHashMap k v -> InsOrdHashMap k' v Source #

Order preserving mapping of keys.

traverseKeys :: (Eq k', Hashable k', Applicative f) => (k -> f k') -> InsOrdHashMap k v -> f (InsOrdHashMap k' v) Source #

Unordered

unorderedTraverse :: Applicative f => (a -> f b) -> InsOrdHashMap k a -> f (InsOrdHashMap k b) Source #

More efficient than traverse, when traversing in insertion order is not important.

unorderedTraverseWithKey :: Applicative f => (k -> a -> f b) -> InsOrdHashMap k a -> f (InsOrdHashMap k b) Source #

More efficient than traverseWithKey, when traversing in insertion order is not important.

Difference and intersection

intersectionWith :: (Eq k, Hashable k) => (v1 -> v2 -> v3) -> InsOrdHashMap k v1 -> InsOrdHashMap k v2 -> InsOrdHashMap k v3 Source #

intersectionWithKey :: (Eq k, Hashable k) => (k -> v1 -> v2 -> v3) -> InsOrdHashMap k v1 -> InsOrdHashMap k v2 -> InsOrdHashMap k v3 Source #

Folds

foldl' :: (a -> v -> a) -> a -> InsOrdHashMap k v -> a Source #

foldMapWithKey :: Monoid m => (k -> a -> m) -> InsOrdHashMap k a -> m Source #

Unordered

unorderedFoldMap :: Monoid m => (a -> m) -> InsOrdHashMap k a -> m Source #

More efficient than foldMap, when folding in insertion order is not important.

unorderedFoldMapWithKey :: Monoid m => (k -> a -> m) -> InsOrdHashMap k a -> m Source #

More efficient than foldMapWithKey, when folding in insertion order is not important.

Filter

filter :: (v -> Bool) -> InsOrdHashMap k v -> InsOrdHashMap k v Source #

filterWithKey :: (k -> v -> Bool) -> InsOrdHashMap k v -> InsOrdHashMap k v Source #

mapMaybe :: (v1 -> Maybe v2) -> InsOrdHashMap k v1 -> InsOrdHashMap k v2 Source #

mapMaybeWithKey :: (k -> v1 -> Maybe v2) -> InsOrdHashMap k v1 -> InsOrdHashMap k v2 Source #

Conversions

keys :: InsOrdHashMap k v -> [k] Source #

elems :: InsOrdHashMap k v -> [v] Source #

toList :: InsOrdHashMap k v -> [(k, v)] Source #

toRevList :: InsOrdHashMap k v -> [(k, v)] Source #

fromList :: forall k v. (Eq k, Hashable k) => [(k, v)] -> InsOrdHashMap k v Source #

Lenses

hashMap :: Iso (InsOrdHashMap k a) (InsOrdHashMap k b) (HashMap k a) (HashMap k b) Source #

This is a slight lie, as roundtrip doesn't preserve ordering.

Debugging

valid :: InsOrdHashMap k v -> Bool Source #

Test if the internal map structure is valid.
