Shout out to cargo-clean-all and cargo-sweep
I've been running out of space on my main drive for awhile and figured my rust build artifacts were probably about 100GB in total.
Ran cargo-clean-all on my workspace and it found 404GB of build artifacts on a 1TB drive.
Wish I'd done it sooner, so this is a PSA if you're continually running out of space and have bunch of old projects lying about
