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.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
  module Proto
    
          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 Ticket, invalid input'
            end
