Demo Segfault about systemstat HOT 2 CLOSED

Hi!

Thanks for trying out this library.

That's a panic, not a segfault, and it's a custom error that says "Not
supported". So, your operating system is not fully supported yet.

I've only implemented full support for FreeBSD and started working on
Linux support (currently, only memory and load_average are working on
Linux).

You can always help with implementing the functionality for different
operating systems ;-)

I tried playing around with your library and was surprised to see one of the few segfaults i've seen in rust and running your demo file too.

Since I rarely run into segfaults im unsure of how to continue, do you have any ideas as to what could be causeing this?

Ok that makes sense. Sorry for my ignorance, I've only been working in rust for about 2 months. Also i'd be glad to help (with what little i can) I've been looking for a smaller project to contribute too lately.
