[ERROR ide_assists::handlers::extract_function] body references two different self params

[mscofield0]

It originated on vscode if it means anything.

Sorry, I don't really have anything besides that. The line in question:

let res = adut!(engine, )
                       ^~~~~~

The adut macro is as follows:

macro_rules! adut {
    ($engine: ident, $id: expr, $msg: expr) => {
        $engine.tick($id, Message::Adut($msg))
    };
}

Here's the error message that rust-analyzer showed:

No idea comes to mind.

[Veykril]

Those are two different things at play here, for one you get a panic in completions, the other is a soft assertion failing in an assist.

Both of these were actually fixed seperately now in #10057 and #10055
