What are some examples of concurrency in Ruby?

Ruby offers several ways to handle concurrency, such as threads, fibers, and the Concurrent Ruby gem. Would you like examples of each?

Yes, please provide examples for threads and fibers.

Sure! For threads, you can use Thread.new to create a new thread. Here's a simple example:

thread = Thread.new do
  puts 'Hello from a thread!'
end
thread.join

For fibers, you can use Fiber.new like this:

fiber = Fiber.new do
  puts 'Hello from a fiber!'
  Fiber.yield
  puts 'Resuming fiber!'
end

fiber.resume
fiber.resume

Would you like to know more about the Concurrent Ruby gem?

Yes, what is the Concurrent Ruby gem?

The Concurrent Ruby gem provides modern concurrency tools for Ruby, including thread pools, futures, and promises. It's designed to make concurrent programming easier and safer. Would you like to see an example of using futures?
