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: gmail.rb
    path of file: ./repos/discourse/lib/imap/providers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Imap
  module Providers
    # Gmail has a special header for both labels (X-GM-LABELS) and their
    # threading system (X-GM-T
    
      def archive(uid)
        thread_id = thread_id_from_uid(uid)
        emails_to_archive = emails_in_thread(thread_id)
        emails_to_archive.each do |email|
          labels = email["LABELS"]
          new_labels = labels.reject { |l| l == "\\Inbox" }
          store(email["UID"], "LABELS", labels, new_labels)
        end
        ImapSyncLog.log(
          "Thread ID #{thread_id} (UID #{uid}) archived in Gmail mailbox for #{@username}",
          :debug,
        )
      end
