build.rs breaks cargo check?

[dgulotta]

When running "cargo check" on a Slint project (using the build.rs file from the tutorial), it does not appear to check any Rust files besides src/main.rs. I can put random garbage in src/lib.rs and it won't complain. If I run "cargo build", it will find the errors in lib.rs. Do I need to change some settings to get "cargo check" to look at lib.rs?

There should be a main.rs, but i wonder why you have a lib.rs for an application (unless you are targetting wasm or android)
In this case, perhaps the lib.rs has a #[cfg] or something like that that makes it not be compiled with cargo check?
because for me it does try to compile a simple lib.rs if i put one there.

Hmm, running "cargo clean" seems to have fixed the issue. I guess it may have just been a random cargo bug.
