fromList :: (Ord k, MonoidNull v) => [(k, v)] -> MonoidMap k vmonoidmap Data.MonoidMap Constructs a MonoidMap from a list of key-value pairs. If the list contains more than one value for the same key, values are combined together in the order that they appear with the (<>) operator. Satisfies the following property for all possible keys k:
get k (fromList kvs) == foldMap snd (filter ((== k) . fst) kvs)
Satisfies the following round-trip property:fromList (toList m) == m
Examples
With String values:>>> fromList [(1,"a"), (2,"x"), (1,"b"), (2,"y"), (1,"c"), (2,"z")] fromList [(1,"abc"), (2,"xyz")]
fromListWith :: (Ord k, MonoidNull v) => (v -> v -> v) -> [(k, v)] -> MonoidMap k vmonoidmap Data.MonoidMap Constructs a MonoidMap from a list of key-value pairs, with a combining function for values. If the list contains more than one value for the same key, values are combined together in the order that they appear with the given combining function. Satisfies the following property for all possible keys k:
get k (fromListWith f kvs) == maybe mempty (foldl1 f) (nonEmpty (snd <$> filter ((== k) . fst) kvs))
toList :: MonoidMap k v -> [(k, v)]monoidmap Data.MonoidMap Converts a MonoidMap to a list of key-value pairs, where the keys are in ascending order. The result only includes entries with values that are not null. Satisfies the following round-trip property:
fromList (toList m) == m
The resulting list is sorted in ascending key order:sortOn fst (toList m) == toList m
