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: convert_file_type.rb
    path of file: ./repos/vets-api/app/uploaders
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module ConvertFileType
  extend ActiveSupport::Concern

  class_methods do
    def tiff?(mimemagic_object: nil, carrier_wave_sanitized_file: nil)
      return mimemagic_object.type == 'image/t
    
  def tiff_or_incorrect_extension?(carrier_wave_sanitized_file)
    mimemagic_object = self.class.inspect_binary carrier_wave_sanitized_file
    self.class.tiff?(
      carrier_wave_sanitized_file:,
      mimemagic_object:
    ) || self.class.incorrect_extension?(
      extension: carrier_wave_sanitized_file.extension,
      mimemagic_object:
    )
  end
