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: shell_reverse_ipv6_tcp.rb
    path of file: ./repos/metasploit-framework/modules/payloads/singles/linux/x64
    
    the code of the file until where you have to start completion: ##
# This module requires Metasploit: https://metasploit.com/download
# Current source: https://github.
    
  def convert_input(value, padding, reverse=false)
      # converts value to comma separated string of
      # zero-padded bytes to be used in the db instruction
      arr = value.to_s(16).rjust(padding, "0").scan(/../)

      if reverse
        arr = arr.reverse
      end
