On a note unrelated to anything, "delete the whole package manager and try again" is a step I commonly perform as a *first* resort with other language package managers such as npm, opam etc. Maybe it would be nice if cargo or cargo clean had a setting for "reset cargo to newborn"

good point. @dsilverstone is the rustup maintainer and probably would have ideas for that. The way I do this is deleting the _other_ folders in `.cargo` (not bin)

Yeah. The thing is if you're deleting subfolders like that you're doing something fiddly and maybe not-future-proofed. Like what if someday later you add a /lib folder that should never be deleted.

If I run cargo --reset-all or rustup reinstall or something and all that does is delete the folders in ~/.cargo other than bin, I can feel confident that whatever it did was "the recommended way", cuz cargo/rustup did it. Anyway this is not very important.

`rustup self uninstall` does *something*, idk if it deletes those things

`rustup self uninstall` will recursively delete all of `$RUSTUP_HOME` and `$CARGO_HOME` (or give it a good go at any rate)

Cool. Uh. Will I have a working rust install afterward?

no, you have to reinstall rustup. this is not precisely what you were looking for, yes :)

'k!

it's worth discussing a `rustup clean` and a `cargo clean-cache` option though
