My favorite flavor of retry logic can be found in the examples/app_log_only.rb file. It demonstrates a dead simple retry method that comes with a :default context and you provide your own logger.

Note: If you are going to use the examples/app_log_only.rb example, and want to capture the last exception that is rais (i.e you ran out of retries) here is how you can do it:

begin
  Retryable.with_context(:default) do
    puts "attempting a call to the faulty service..."
    fs.call
  end
rescue StandardError => e
  # you have to capture the entire block other wise it will interfere with the retry logic
  puts "ran out of retries, here is the exception: #{e}"
end
