Module: Resto::Copy

Defined in:
lib/resto/extra/copy.rb

Overview

Note:

This module is used internally by these classes/modules: Resto::ClassMethods (see method Resto::ClassMethods#request, and Resto::ClassMethods#base_response). Resto::Request::Base (see method Request::Base#construct_path).

This module has two helper methods that handles the process of copying the Request::Base object and Response::Base object correctly.
