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: relativize_paths.rb
    path of file: ./repos/nanoc/nanoc/lib/nanoc/filters
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Nanoc::Filters
  # @api private
  class RelativizePaths < Nanoc::Filter
    identifier :r
    
    def relativize_node(node, selector_type)
      case selector_type
      when :basic
        relative_path_to(node.content)
      when :srcset
        handle_srcset_node(node)
      else
        raise Nanoc::Core::Errors::InternalInconsistency, "Unsupported selector type #{selector_type.inspect} in #{self.class}"
      end
