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: conflict_files_stitcher.rb
    path of file: ./repos/gitlabhq/lib/gitlab/gitaly_client
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
  module GitalyClient
    class ConflictFilesStitcher
      include Enumerable

      attr_reader :gital
    
      def file_from_gitaly_header(header)
        Gitlab::Git::Conflict::File.new(
          Gitlab::GitalyClient::Util.git_repository(gitaly_repo),
          header.commit_oid,
          conflict_from_gitaly_file_header(header),
          ''
        )
      end
