map :: (a -> b) -> KeyMap a -> KeyMap b
aeson Data.Aeson.KeyMap
Map a function over all values in the map.
mapKeyVal :: (Key -> Key) -> (v1 -> v2) -> KeyMap v1 -> KeyMap v2
aeson Data.Aeson.KeyMap
Transform the keys and values of a KeyMap.
mapMaybe :: (a -> Maybe b) -> KeyMap a -> KeyMap b
aeson Data.Aeson.KeyMap
Map values and collect the Just results.
mapMaybeWithKey :: (Key -> v -> Maybe u) -> KeyMap v -> KeyMap u
aeson Data.Aeson.KeyMap
Map values and collect the Just results.
mapWithKey :: (Key -> a -> b) -> KeyMap a -> KeyMap b
aeson Data.Aeson.KeyMap
Map a function over all values in the map.
mapFromJSONKeyFunction :: (a -> b) -> FromJSONKeyFunction a -> FromJSONKeyFunction b
aeson Data.Aeson.Types
Same as fmap. Provided for the consistency with ToJSONKeyFunction.
module Data.Aeson.KeyMap
aeson
An abstract interface for maps from JSON keys to values.
data KeyMap v
aeson Data.Aeson.KeyMap
A map from JSON key type Key to v.

aeson Data.Aeson.KeyMap
fromHashMap :: HashMap Key v -> KeyMap v
aeson Data.Aeson.KeyMap
Convert a HashMap to a KeyMap.
fromHashMapText :: HashMap Text v -> KeyMap v
aeson Data.Aeson.KeyMap
Convert a HashMap Textto a KeyMap.
fromMap :: Map Key v -> KeyMap v
aeson Data.Aeson.KeyMap
Convert a Map to a KeyMap.
fromMapText :: Map Text v -> KeyMap v
aeson Data.Aeson.KeyMap
Convert a Map Textto a KeyMap.
toHashMap :: KeyMap v -> HashMap Key v
aeson Data.Aeson.KeyMap
Convert a KeyMap to a HashMap.
toHashMapText :: KeyMap v -> HashMap Text v
aeson Data.Aeson.KeyMap
Convert a KeyMap to a HashMap Text.
toMap :: KeyMap v -> Map Key v
aeson Data.Aeson.KeyMap
Convert a KeyMap to a Map.
toMapText :: KeyMap v -> Map Text v
aeson Data.Aeson.KeyMap
Convert a KeyMap to a Map Text.
contramapToJSONKeyFunction :: (b -> a) -> ToJSONKeyFunction a -> ToJSONKeyFunction b
aeson Data.Aeson.Types
Contravariant map, as ToJSONKeyFunction is a contravariant functor.
