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: client_mixin.rb
    path of file: ./repos/metasploit-framework/lib/rex/proto/mssql
    
    the code of the file until where you have to start completion: module Rex
module Proto
module MSSQL
# A base mixin of useful mssql methods for parsing structures etc
module Cl
    
  def mssql_parse_error(data, info)
    len  = data.slice!(0, 2).unpack('v')[0]
    buff = data.slice!(0, len)

    errno, state, sev, elen = buff.slice!(0, 8).unpack('VCCv')
    emsg = buff.slice!(0, elen * 2)
    emsg.gsub!("\x00", '')

    info[:errors] << "SQL Server Error ##{errno} (State:#{state} Severity:#{sev}): #{emsg}"
    info
  end
