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: helix_runtime.rb
    path of file: ./repos/helix/ruby/lib
    
    the code of the file until where you have to start completion: require "helix_runtime/version"
require "helix_runtime/platform"
require 'helix_runtime/project'
require 'helix_runtime/parent_project'

begin
  require "helix_runtime/native"
rescue LoadError
  warn "Unable to load helix_runtime/native. Please run `rake compile` in #{File.expand_path("../..", __FILE__)}."
end

mod
    
  def self.copy_dll
    if IS_WINDOWS
      so_path = File.expand_path("../helix_runtime/native.#{Platform.dlext}", __FILE__)
      raise "Unable to find native bundle at #{so_path}" unless File.exists?(so_path)

      bindir = RbConfig::CONFIG['bindir']
      raise "Unable to determine Ruby bindir" unless bindir

      FileUtils.cp so_path, File.join(bindir, dll_filename)
    else
      # No-op
    end
