Examples

Stream.unfold/2

require 'elixir/stream'

include Elixir

Fib = Stream.unfold [0, 1] do |a, b|
  [a, [b, a + b]]
end

Fib.size
#=> Infinity

Fib.take 5
#=> [0, 1, 1, 2, 3]

Agent and Task

require 'elixir/agent'
require 'elixir/task'

include Elixir

status, agent = Agent.start { 0 }
#=> [:ok, #<Concurrent::Atomic:...>]

Agent.cast(agent) { |value| value + 42 }
#=> :ok

Agent.get agent, &:next
#=> 43

task = Task.async do
  sleep 0.5

  Agent.get agent, &:itself
end
#<Concurrent::IVar:...>

Task.await task
#=> 42
