How can I use Celluloid in my Ruby application?

You can use Celluloid to manage concurrency in Ruby by creating actors that handle tasks asynchronously. First, add the Celluloid gem to your Gemfile.

What are actors in Celluloid?

Actors in Celluloid are objects that encapsulate state and behavior, allowing you to run methods concurrently without worrying about thread safety.

Can you give me a simple example of using an actor?

Sure! Here's a simple example:

require 'celluloid'

class Counter
  include Celluloid

  def count
    10.times do |i|
      puts "Count: \\#{i}"
      sleep 1
    end
  end
end

counter = Counter.new
counter.async.count

What happens if I try to access shared data from multiple actors?

If multiple actors try to access shared data, you may encounter race conditions. It's best to use message passing to communicate between actors instead.
