How to cargo clean only a sub crate of a workspace?
I tried cargo clean -p cratename but it didn't work..

I wanted to run clippy on the subcrate without having to clean & rebuild the main crate because rebuilding takes hours. But clippy just said Finished dev [optimized + debuginfo] target(s) in 7.01s but it didn't say "compiling ...", so I want to clean only the sub crate.

It should work. Can you say more about what happened?

In particular for check, you should see this:

1. Notice target/debug/deps/libNAME-*.rmeta exists from previous check runs.
2. Run cargo clean -p NAME.
3. Check if target/debug/deps/libNAME-*.rmeta has been removed.
4. Running cargo check -p NAME should re-check the NAME package and regenerate the rmeta file.

Why check? I'm talking about clean :)

Oh...some reason my brain translated clippy to check (they use similar mechanisms underneath). Just substitute the word "clippy" for "check", it's the same (they both generate rmeta files).

Are you using "cargo clippy" from the command-line? Or maybe using the new integrated rls support?

The other way to rerun Clippy is to touch the lib.rs/main.rs of the crate.
