README
SortedSet
A sorted set library for Elixir. Implements the Set protocol.
Installation
Add the following to deps section of your mix.exs:
{:sorted_set, "~> 1.0"}
and then mix deps.get. That's it!
Generate the documentation with mix docs.
About
Sorted sets are backed by a red-black tree, providing lookup in O(log(n)). Size is tracked automatically, resulting in O(1) performance.
Basic Usage
SortedSet implements the Set behaviour, Enumerable, and Collectable.
SortedSet.new()
|> Set.put(5)
|> Set.put(1)
|> Set.put(3)
|> Enum.reduce([], fn (element, acc) -> [element*2|acc] end)
|> Enum.reverse
# => [2, 6, 10]
Custom Comparison
Sorted Set can also take a custom :comparator function to determine ordering. The
function should accept two terms and
- return
0if they are considered equal - return
-1if the first is considered less than or before the second - return
1if the first is considered greater than or after the second
This function is passed on to the underlying red-black tree implementation implemetation. Otherwise, the default Erlang term comparison is used (with an extra bit to handle edgecases — see note in RedBlackTree README.)
SortedSet.new([:a, :b, :c], comparator: fn (term1, term2) ->
RedBlackTree.compare_terms(term1, term2) * -1
end)
# => #SortedSet<[:c, :b, :a]>
