    let ob_base: PyObject = unsafe { std::mem::zeroed() };

    let mut o = PyASCIIObject {

    }

What is the error? If there is no error, how does it look? Can you attach a screenshot?

[clin1234]

The error is that cargo could not be found, even though I installed the toolchain at /home/codespace/.cargo/bin/ through rustup

[ChayimFriedman2]

If you add "rust-analyzer.server.extraEnv": {"PATH": "/home/codespace/.cargo/bin"}, does it work?
