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: rust.rb
    path of file: ./repos/devdocs/lib/docs/scrapers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Docs
  class Rust < UrlScraper
    self.type = 'rust'
    self.release = '1.75.0'
    self.base_url = 'https://doc.rust-lang.org/'
    self.root_path = 'b
    
    def get_latest_version(opts)
      doc = fetch_doc('https://www.rust-lang.org/', opts)
      label = doc.at_css('.button-download + p > a').content
      label.sub(/Version /, '')
    end

    REDIRECT_RGX = /http-equiv="refresh"/i
    NOT_FOUND_RGX = /<title>Not Found<\/title>/

    def process_response?(response)
      !(response.body =~ REDIRECT_RGX || response.body =~ NOT_FOUND_RGX || response.body.blank?)
    end

    def parse(response) # Hook here because Nokogori removes whitespace from headings
      response.body.gsub! %r{<h[1-6] class="code-header">}, '<pre class="code-header">'
      super
    end
