Didn't know about linter-rust. Thanks for sharing.

It didn't occur to me that: ownership transfer means variable cannot be used, so if it's used means there's an error, so checking for error itself gives you the information that you cannot use it. So highlighting error can be used instead of the specific ownership transfer.

I don't know of any other specific cases where there's no error, but it would be helpful to have a different color for certain ownership semantics.
