Please remove only the relevant target directory before using --time

[heidezomp]

The new --time feature is cool! But it would be helpful if instead of running a full cargo clean beforehand, it would only remove the relevant directory (e.g. target/debug). Now my release build and documentation are also gone, and those take a pretty long time to build from scratch on my old and slow laptop.

Looks like I can remove release and/or doc, but not just debug. At least I can't find such an option. So I can add support for removing only the release dir while running cargo-bloat --release and in debug it will remove everything as previously.

And I don't think that removing the target dir without cargo is a good idea.

I think you definitely want to go through cargo clean, otherwise you'll run into weird cases with things like CARGO_TARGET_DIR.

I see what you mean with the cargo clean options. I agree with both of you on going through cargo clean. I think having the desired behavior only in release mode is better than nothing, so if you can add support for that, that would be great! 😄

In the mean time I will see whether there is an issue on adding the desired behavior to cargo clean; if not, I'll add one. The currently provided options seem inconsistent to me anyway.

There didn't seem to be an issue about this yet, so I opened rust-lang/cargo#7021 😄
