How do I get the number of cache hits?

[drag05]

I would like to get the number of cache hits to test a newly cached function.

I know one way would be to set up a logfile. I wonder if there is any other, more elegant way to get the hits without using the logfile?
I've seen in a piece of code a utility function to the likes of memoise::stats(memoizedFun) but no-longer exists. The code example showed the number of cache hits among other things.

I have also seen a memoise:::hash_list() function that would allow inserting cache key labels which would identify each function in scripts having multiple memoised functions which, also no-longer exists.

Is this because I built the cache with cachem package?

Thank you!
