-module Faraday
-  # Catches exceptions and retries each request a limited number of times.
-  #
-  # By default, it retries 2 times and handles only timeout exceptions. It can
-  # be configured with an arbitrary number of retries, a list of exceptions to
-  # handle, a retry interval, a percentage of randomness to add to the retry
-  # interval, and a backoff factor.
-  #
-  # Examples
-  #
-  #   Faraday.new do |conn|
-  #     conn.request :retry, max: 2, interval: 0.05,
-  #                          interval_randomness: 0.5, backoff_factor: 2
-  #                          exceptions: [CustomException, 'Timeout::Error']
-  #     conn.adapter ...
-  #   end
-  #
-  # This example will result in a first interval that is random between 0.05 and 0.075 and a second
-  # interval that is random between 0.1 and 0.15
