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: source.rb
    path of file: ./repos/ruby-vips/lib/vips
    
    the code of the file until where you have to start completion: # This module provides an interface t
    
    def self.new_from_file(filename)
      raise Vips::Error, "filename is nil" if filename.nil?
      ptr = Vips.vips_source_new_from_file filename
      raise Vips::Error if ptr.null?

      Vips::Source.new ptr
    end
