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: turbo_dev.rb
    path of file: ./repos/discourse/lib/middleware
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
module Middleware
  # Cheat and bypass Rails in development mode if the client attempts to download a static asset
  # that's 
    
    def call(env)
      root = "#{GlobalSetting.relative_url_root}/assets/"
      is_asset = env["REQUEST_PATH"] && env["REQUEST_PATH"].starts_with?(root)

      # hack to bypass all middleware if serving assets, a lot faster 4.5 seconds -> 1.5 seconds
      if (etag = env["HTTP_IF_NONE_MATCH"]) && is_asset
        name = env["REQUEST_PATH"][(root.length)..-1]
        etag = etag.gsub "\"", ""
        asset = Rails.application.assets.find_asset(name)
        return 304, {}, [] if asset && asset.digest == etag
      end
