How can I use the Ruby Async gem for advanced concurrency?

The Ruby Async gem allows you to write concurrent code in a more manageable way. You can use it to handle multiple tasks simultaneously without blocking the main thread.

Can you provide an example of using Async with HTTP requests?

Sure! You can use the Async::HTTP module to make non-blocking HTTP requests. Here's a simple example:

require 'async/http'

Async do
  response = Async::HTTP.get('http://example.com')
  puts response.read
end

What about error handling in Async?

Error handling can be done using begin...rescue blocks within your Async block. This way, you can catch exceptions without crashing your application.

Are there any performance considerations I should be aware of?

Yes, while Async can improve performance by handling multiple tasks, be cautious of resource limits and ensure that your code is efficient to avoid overwhelming the system.
