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: file_fixture_helpers.rb
    path of file: ./repos/alonetone/spec/support
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module RSpec
  module Support
    module FileFixtureHelpers
      def file_fixture(path)
        file
    
      def file_fixture_asset(path, filename: nil, content_type: nil, user: nil)
        asset = process_file_fixture_uploaded_file(
          path, filename: filename, content_type: content_type, user: user
        )
        raise(
          ArgumentError,
          "Can't process file fixture at `#{file_fixture_pathname(path).to_s}'"
        ) if asset.nil?
        asset
      end
