function-restore

Restore libraries from the serialized payload.

You can use the optional policy argument to provide a policy for handling existing libraries. The following policies are allowed:

• APPEND: appends the restored libraries to the existing libraries and aborts on collision. This is the default policy.
• FLUSH: deletes all existing libraries before restoring the payload.
• REPLACE: appends the restored libraries to the existing libraries, replacing any existing ones in case of name collisions. Note that this policy doesn't prevent function name collisions, only libraries.
