empty :: KeyMap v #

Construct an empty map.

null :: KeyMap v -> Bool #

Is the map empty?

singleton :: Key -> v -> KeyMap v #

Construct a map with a single element.

fromList :: [(Key, v)] -> KeyMap v #

Construct a map with the supplied mappings. If the list contains duplicate mappings, the later mappings take precedence.

>>> fromList [("a", 'x'), ("a", 'y')]
fromList [("a",'y')]

toList :: KeyMap v -> [(Key, v)] #

Return a list of this map's keys and elements.

The order is not stable. Use toAscList for stable ordering.
