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: for_package.rb
    path of file: ./repos/open-build-service/src/api/app/models/local_build_statistic
    
    the code of the file until where you have to start completion: module LocalBuildStatistic
  class ForPackage
    include ActiveModel::Model
    attr_accessor :package, :project, :reposito
    
    def statistic
      result = backend_statistics
      return if result.blank?

      disk = result.dig('disk', 'usage')
      memory = result.dig('memory', 'usage')
      times = result.get('times')
      local_statistics = LocalStatistic.new

      if disk
        local_statistics.disk = LocalBuildStatistic::Package::Disk.new(size: disk.dig('size', '_content'),
                                                                       unit: disk.dig('size', 'unit'),
                                                                       io_requests: disk['io_requests'],
                                                                       io_sectors: disk['io_sectors'])
      end
