You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: power_interface.rb
    path of file: ./repos/foreman/app/models/concerns/hostext
    
    the code of the file until where you have to start completion: module Hostext
  module PowerInterface
    extend ActiveSupport::Concern

    
    
    def supports_power_and_running?
      return false unless supports_power?
      power.ready?
      # return false if the proxyapi/bmc raised an error (and therefore do not know if power is supported)
    rescue ProxyAPI::ProxyException
      false
    end
  end
