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: connection.rb
    path of file: ./repos/anycable-rails/spec/dummy/app/channels/application_cable
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    class << self
      def e
    
    def verify_user
      return env["warden"]&.user if env["warden"]&.user

      username = session[:username] || cookies[:username]
      return reject_unauthorized_connection unless username

      self.token = session[:token] || request.params[:token]

      User.find_by!(name: username, secret: token)
    end
