+Copy

+Copy can be called to copy an object or update the metadata on the given items.
+
+Each element of the object list may be a plain string of the object name, or a
+``SwiftCopyObject`` that allows finer control over the options applied to each
+of the individual copy operations (destination, fresh_metadata, options).
+
+Destination should be in format /container/object; if not set, the object will be
+copied onto itself. Fresh_metadata sets mode of operation on metadata. If not set,
+current object user metadata will be copied/preserved; if set, all current user
+metadata will be removed.
+
+Returns an iterator over the results generated for each object copy (and may
+also include the results of creating destination containers).
+
+When a string is given for the object name, destination and fresh metadata will
+default to None and None, which result in adding metadata to existing objects.
+
+Successful copy results are dictionaries as described below:
+
+.. code-block:: python
+
+ {
+ 'action': 'copy_object',
+ 'success': True,
+ 'container': <container>,
+ 'object': <object>,
+ 'destination': <destination>,
+ 'headers': {},
+ 'fresh_metadata': <boolean>,
+ 'response_dict': <HTTP response details>
+ }
+
+Any failure in a copy operation will return a failure dictionary as described
+below:
+
+.. code-block:: python
+
+ {
+ 'action': 'copy_object',
+ 'success': False,
+ 'container': <container>,
+ 'object': <object>,
+ 'destination': <destination>,
