Hi,

I am seeing this trace occasionally

@jgrund, thanks for the report! I'll fix the problem anyway, but it would be great if you could provide a cargo command output that leads to this problem.

First off, thanks for working on and maintaining this plugin; it's been nice to use.

Here's a reduced case.

1. Create a .rs file that contains just

s

2. Run a build. In this case I'm running:

cargo build --message-format=json --verbose

Here is the output:

1

Rust
Error

Thanks for the example! The fix is on the way.
