How to print `sync::cache` state #26

Closed kakoc closed 2 years ago

kakoc commented 2 years ago

Suppose I have a sync::Cache<_, _> and I'd like to display its content(for example for debugging purposes). How can I do that? I didn't find any way.

Hi, which stats you want to print? Currently, this crate does not provide any iter for users to view all of the data in the cache.

I'd like to see key: value pairs

al8n commented 2 years ago

If you want to see how many key: value pairs are in the cache, I can add the functionality. But if you want to see something like key1: value1 key2: value2, and etc, we seem to cannot do it because of the cache design. But you can implement a custom CacheCallback. I think it can give you the equivalent functionality.
