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: top_level_describe.rb
    path of file: ./repos/brew/Library/Homebrew/vendor/bundle-standalone/ruby/2.3.0/gems/rubocop-rspec-1.31.0/lib/rubocop/rspec
    
    the code of the file until where you have to start completion: module RuboCop
  module RSpec
    # Helper methods for top level describe cops
  
    
      def top_level_nodes
        nodes = describe_statement_children(root_node)
        # If we have no top level describe statements, we need to check any
        # blocks on the top level (e.g. after a require).
        if nodes.empty?
          nodes = root_node.each_child_node(:block).flat_map do |child|
            describe_statement_children(child)
          end
        end
