Code

Supposedly this snipped is critical:
impl<T: SPort + 'static> Serial<T>
   pub fn split_method(
        &mut self,
    ) -> (
        impl Fn(&mut Rx<dyn SPortRx>) -> std::result::Result<u8, nb::Error<std::io::Error>>,
        impl Fn(&mut Tx<T>, u8) -> std::result::Result<(), nb::Error<std::io::Error>>,
    ) {
        let rx = Rx::read;
        let tx = Tx::write;
        (rx, tx)
    }
}

Can you check on beta btw ? It should be fixed there.

rustup install beta should work, and then you can run your previous cargo/rustc commands that caused the error above, but with +beta to make sure that version is used, like cargo +beta check. It should show a compilation error rather than this "cannot relate bound region" ICE.

No. It's local right now. And the source code will be in the comnpabnies own GitLab server. The company right now is not inclined to contribute to the open source community (the dev department is working on that ....)

Moreove my current code is mostly nonsense, anyways.

I in fact would like to be able to run the beta compiler though. (This is on Windows in the VSCode terminal. Ist that a problem ? I do have a Linux VM and I also could install the Windows Linux Subsystem.)

rustc +beta -vV and cargo +beta -vV should work wherever rustup is in the $path.

In any case, I'm sure this issue is solved on beta, and will become fixed on stable in 1.69 releasing in a couple weeks.

rustc +beta -vV
does work

rustup 1.25.2 (17db695f1 2023-02-01)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.69.0-beta.6 (6a97551bc 2023-04-02)`

cargo +beta -vV
does not work

$ cargo  +beta -vV
error: no such command: `+beta`
        Cargo does not handle `+toolchain` directives.
        Did you mean to invoke `cargo` through `rustup` instead?

$ rustup +beta check
