Ability to get an owned `Disk` out of `Disks`

[dlowe]

I'm using sysinfo to report the disk space (total & available) for one disk of interest, over time, in an Fn closure, in a long-lived, multi-threaded process. It's possible, but it's surprisingly convoluted because (AFAICT) there's no way for me to get an owned Disk.

At the moment:

• on startup, call Disks::new_with_refreshed_list() (In a mutex, in a lazy_static)
• each time my closure is called to recompute totals:
  • acquire the mutex lock
  • iterate over Disks::list_mut() to find the one I'm interested in (always the same disk!)
  • call Disk::refresh() on the selected Disk

Basically: I want to do the disk-selection on startup, but I can't.

I'd be more than happy to contribute a fix. Would it be welcome? Any guidance on how to approach it? The most obvious thing would be to make Disk be + Clone, but I have no idea if that's possible.

You can convert your Disks into a Vec<Disk> (see documentation here).

🤦 thank you!
