Questions about how to check the cashe usage and, about specifying the cache size

[para-d]

Hi Team,

I've developed an application and used FastCache as an in-memory data store. So far, everything works fine. One thing I'm struggling is to figure out is how to see the cache usage in megabytes.

So,

1. Is there a way to get the cache usage (not the allocation) and/or the free quota?
2. If it's not possible at the moment, would such a feature be made available in the future?

There's some confusion in the documentation as well, when creating a cache using fastcache.New(maxBytes)
(https://pkg.go.dev/github.com/VictoriaMetrics/fastcache#New)

3. If we need a cache of 64MB, should we specify maxBytes as 64 or 64000000?

I'll be using it as 64000000. The given example (32MB) is given in MB that's why I got confused.
