Duplicate of #192. I'd guess you are running an old rust-analyzer and/or intellij that has corrupted the target directory, but if not, you'll need to provide repro steps in that issue.

@dtolnay Hm, you're correct that the problem appears to be caused by rust-analyzer, but I wouldn't describe this as an old version. cargo clean fixes it. I assume rust-analyzer 1.65 or 1.66 has a fix?

ipc-rpc> rustup run stable rust-analyzer --version
rust-analyzer 1.64.0 (a55dd71d 2022-09-19)

It's odd, I just setup this machine. It's never had a different toolchain version on it. Still I can't reproduce the issue on demand. I'll update the other issue if I come up with something.

a55dd71d contains a rust-analyzer from July. I feel like you should only use that if you enjoy hitting all the issues that have been fixed in the last nearly 3 months. https://rust-analyzer.github.io/manual.html#installation explains the supported installation options.
