README
ParallelStream 
Parallelized stream implementation for elixir
What does it do?
Parallelize some stream operations in Elixir whilst keeping your stream in order. Operates with a worker pool.
How do I get it?
Add
{:parallel_stream, "~> 1.0.5"}
to your deps in mix.exs like so:
defp deps do
[
{:parallel_stream, "~> 1.0.5"}
]
end
Note: Elixir 1.1.0 is required
How to use
Do this to parallelize a map:
stream = 1..10 |> ParallelStream.map(fn i -> i * 2 end)
stream |> Enum.into([])
[2,4,6,8,10,12,14,16,18,20]
The generated stream is sorted the same as the input stream.
More supported functions are each (to produce side-effects):
1..100 |> ParallelStream.each(&IO.inspect/1)
filter:
stream = 1..20 |> ParallelStream.filter(fn i -> i |> rem(2) == 0 end)
stream |> Enum.into([])
[2,4,6,8,10,12,14,16,18,20]
and filter's counterpart, reject:
stream = 1..20 |> ParallelStream.reject(fn i -> i |> rem(2) == 0 end)
stream |> Enum.into([])
[1,3,5,7,9,11,13,15,17,19]
