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: helpers.rb
    path of file: ./repos/rspec-rails-swagger/lib/rspec/rails/swagger
    
    the code of the file until where you have to start completion: module RSpec
  module Rails
    module Swagger
      module Helpers

        #   /pets: (Path Item)

              # To make a request we need:
              # - the details we've collected in the metadata
              # - parameter values defined using let()
              # RSpec tries to limit access to metadata inside of it() / before()
              # / after() blocks but that scope is the only place you can access
              # the let() values. The solution the swagger_rails dev came up with
              # is to use the example.metadata passed into the block with the
              # block's scope which has access to the let() values.
