toList

List of elements of a structure, from left to right. If the entire list is intended to be reduced via a fold, just fold the structure directly bypassing the list.

Examples

Basic usage:

>>> toList Nothing
[]

>>> toList (Just 42)
[42]

>>> toList (Left "foo")
[]

>>> toList (Node (Leaf 5) 17 (Node Empty 12 (Leaf 8)))
[5,17,12,8]

For lists, toList is the identity:

>>> toList [1, 2, 3]
[1,2,3]

Convert a stream to a normal list efficiently.

The toList function extracts a list of Item l from the structure l. It should satisfy fromList . toList = id.

Convert an immutable array to a list.

Convert the map to a list of key/value pairs. Subject to list fusion.

toList (fromList [(5,"a"), (3,"b")]) == [(3,"b"), (5,"a")]
toList empty == []

Convert the set to a list of elements. Subject to list fusion.

Convert the map to a list of key/value pairs. Subject to list fusion.

toList (fromList [(5,"a"), (3,"b")]) == [(3,"b"), (5,"a")]
toList empty == []

Convert the set to a list of elements. Subject to list fusion.

Return a list of this map's keys and elements. The order is not stable. Use toAscList for stable ordering.
