Any way to see the list of channels a client is subscribed to or the list of clients subscribed to a channel?

What is the easiest way for me to to see the list of channels a client is subscribed, as well as the list of clients subscribed to a channel?

For example, before allowing a client to publish to a channel, I may want to check that it is first subscribed to the channel

I think this was answered before. The only way, for now at least, to achieve that, is to track it yourself with lists/dictionaries.

I see. The library itself must keep track of this information somewhere though, right? Is it just not possible to access this information?

It's not possible right now, but something like that could be added.
