how to check if fragment_cache exists in Rails 5.1

I have a slim fragment like this:

- cache [@user, :user_show, 'v2'] do

but we are concerned about our hit / miss rate and would like to log this. Is there an easy way to do this? I was thinking I could could Rails.cache.exist? but I'd need to know more than what I have here (namely the template digest). Any ideas how to check for the existence of a cached fragment?

I think you can use controller.fragment_exist? for that https://apidock.com/rails/v5.2.3/AbstractController/Caching/Fragments/fragment_exist%3F

And you should be able to use cache_fragment_name to get the actual key https://apidock.com/rails/v5.2.3/ActionView/Helpers/CacheHelper/cache_fragment_name
