I just used the slint-rust-template and got a bunch of errors from the start. #6705

Closed 6p5ra closed 3 weeks ago

6p5ra commented 3 weeks ago

I ran everything as specified in the template's readme.

cargo build and then cargo run.

In the PROBLEMS tab of my IDE VS Code, I got a huge list of errors:

cargo build and then cargo run.

But that worked fine, right?

In the PROBLEMS tab of my IDE VS Code, I got a huge list of errors:

I've never seen that. But it seems like rust-analyzer report errors in the doctest from the dependencies. These can't work because they require dev-dependencies that are not loaded transitively, by design. So this is, i'd say, a bug of rust analyzer that it tries to compile the doctest in dependencies.

ogoffart commented 3 weeks ago

I don't think this is related to a problem in Slint. Looks like a bug in rust-analyzer to me.

Yes, you are absolutely correct. Reinstalling rust on the system fixed the problem. Thanks for the response.
