How can I clean cargo stuff?

Question

I tried to install Parity (an Ethereum client) on my CHIP computer (similar to a Raspberry Pi with 4GB memory). I cloned the repository and ran

cargo build --release

After a while I noticed that about 40% of the memory was used and I stopped the installation process. There was only 20% used before, so now I want to clean all of this Rust stuff. How can I do that?

Cargo places all temporary build files into the target/ directory. Sometimes, if not already present, Cargo also creates a Cargo.lock file. The directory can be removed by executing:

cargo clean

Cargo also saves the package index and the source code of dependencies globally in ~/.cargo/registry/.

Well, the problem is that I've removed Parity folder with rm -rf :( So now, when I'm running cargo clean, there is an error "could not fnid 'Cargo.toml'" – Sergey Potekhin Oct 30 '16 at 15:30
@SergeyPotekhin If you've deleted the project directory, you've already done the equivalent of `cargo clean` and more. The global cache is probably your next place to look – Shepmaster Oct 30 '16 at 21:59

Is it safe to do `rm -rf ~/.cargo/registry`? – Aaron Miller Oct 05 '21 at 20:28

@AaronMiller I'm actually not 100% sure. I think it's safe, but better ask a dedicated question! – Lukas Kalbertodt Oct 06 '21 at 14:12
@AaronMiller, [this other SO answer](https://stackoverflow.com/a/51919907) suggests it's OK to do that. – TheDudeAbides Dec 26 '22 at 09:02
