Need some data filter from meta data which came from custom module

I am getting following output from my ansible custom module ‘{‘failed’: False, ‘meta’: {‘Unused Policy Rules IDS’: [0, 3, 4, 5, 6]}, ‘changed’: False}’ to one variable .I need to fetch only “{‘Unused Policy Rules IDS’: [0, 3, 4, 5, 6]”}.Can anyone help to resolve this issue.
