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: sync_from_file.rb
    path of file: ./repos/motor-admin-rails/lib/motor/configs
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Motor
  module Configs
    module SyncFromFile
      MUTEXT = Mutex.new
      FILE_TIMESTAMPS_STORE = ActiveSupport::Cache::MemoryStore.new(size: 1.megabyte)

      module_function

      def call(with_exception: false)
        MUTEXT.synchronize do
          file = Pathname.new(Motor::Configs.file_path)

          file_timestamp =
            begin
              file.ctime
            rescue Errno::ENOENT
 
    
      def call(with_exception: false)
        MUTEXT.synchronize do
          file = Pathname.new(Motor::Configs.file_path)

          file_timestamp =
            begin
              file.ctime
            rescue Errno::ENOENT
              raise if with_exception

              nil
            end

          next unless file_timestamp

          FILE_TIMESTAMPS_STORE.fetch(file_timestamp.to_s) do
            Motor::Configs::SyncFromHash.call(
              YAML.safe_load(file.read, permitted_classes: [Time, Date])
            )
          end
        end
