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: uint32.rb
    path of file: ./repos/hrr_rb_ssh/lib/hrr_rb_ssh/data_types
    
    the code of the file until where you have to start completion: module HrrRbSsh
  class Da
    
      def self.encode arg
        case arg
        when 0x0000_0000..0xffff_ffff
          [arg].pack("N")
        else
          raise ArgumentError, "must be in #{0x0000_0000}..#{0xffff_ffff}, but got #{arg.inspect}"
        end
