Methods

icode :: BiMap a b -> S Int32 Source #

icod_ :: BiMap a b -> S Int32 Source #

value :: Int32 -> R (BiMap a b) Source #

lookup :: Ord a => a -> BiMap a b -> Maybe b Source #

Lookup. O(log n).

invLookup :: Ord b => b -> BiMap a b -> Maybe a Source #

Inverse lookup. O(log n).

empty :: BiMap a b Source #

Empty bimap. O(1).

singleton :: a -> b -> BiMap a b Source #

Singleton bimap. O(1).

insert :: (Ord a, Ord b) => a -> b -> BiMap a b -> BiMap a b Source #

Insert. Overwrites existing value if present. O(Map.insert).

union :: (Ord a, Ord b) => BiMap a b -> BiMap a b -> BiMap a b Source #

Left-biased Union. O(Map.union).

fromList :: (Ord a, Ord b) => [(a, b)] -> BiMap a b Source #

Does not check for actual bijectivity of constructed finite map. O(n log n)

toList :: BiMap a b -> [(a, b)] Source #

Turn into list, sorted ascendingly by first value. O(Map.toList)
