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: ticket_enc_part.rb
    path of file: ./repos/metasploit-framework/lib/rex/proto/kerberos/model
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-

module Rex::P
    
    def decode(input)
      case input
      when String
        decode_string(input)
      when OpenSSL::ASN1::ASN1Data
        decode_asn1(input)
      else
        raise ::Rex::Proto::Kerberos::Model::Error::KerberosDecodingError, 'Failed to decode TicketEncPart, invalid input'
      end
