From 4a4c3f9b6389168033843814ad45e69bf0b92b1d Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Wed, 9 Mar 2022 16:01:32 +0000 Subject: list-objects-filter-options: create copy helper As we add more embedded members with type 'struct list_objects_filter_options', it will be important to easily perform a deep copy across multiple such structs. Create list_objects_filter_copy() to satisfy this need. This method is recursive to match the recursive nature of the struct.
