A collection of conditional functions for maipulating dictionaries
insertIf : Basics.Bool -> comparable -> v -> Dict comparable v -> Dict comparable v
Conditional dict insertion
insertWhen : Maybe comparable -> v -> Dict comparable v -> Dict comparable v
Insert into dict, if the key is not Nothing
insertWhenValue : comparable -> Maybe v -> Dict comparable v -> Dict comparable v
Insert into dict, if the value is not Nothing
updateIf : Basics.Bool -> comparable -> (Maybe v -> Maybe v) -> Dict comparable v -> Dict comparable v
Conditional dict update
updateWhen : Maybe comparable -> (Maybe v -> Maybe v) -> Dict comparable v -> Dict comparable v
Update dict, if the key is not Nothing
updateWhenValue : comparable -> Maybe (Maybe v -> Maybe v) -> Dict comparable v -> Dict comparable v
Update dict, if the value is not Nothing
removeIf : Basics.Bool -> comparable -> Dict comparable v -> Dict comparable v
Conditional dict removal
removeWhen : Maybe comparable -> Dict comparable v -> Dict comparable v
Remove an entry from a dict, if the key is not Nothing
mapIf : Basics.Bool -> (k -> a -> a) -> Dict k a -> Dict k a
Apply the mapping function only if the first parameter evalutes to True.
filterIf : Basics.Bool -> (comparable -> v -> Basics.Bool) -> Dict comparable v -> Dict comparable v
Conditional filtering.
unionIf : Basics.Bool -> Dict comparable v -> Dict comparable v -> Dict comparable v
If the first parameter evalutes to True, then both Dicts are unified, otherwise the second Dict defines the result
intersectIf : Basics.Bool -> Dict comparable v -> Dict comparable v -> Dict comparable v
Conditional intersection.
