cargo fmt and vs code autosave formatting result in different outputs

[dreuter]

Hi :)

Thanks for this great vs code extension :)

I am using vs code with this version:

Version 1.18.1
Commit 929bacba01ef658b873545e26034d1a8067445e9
Date 2017-11-16T18:34:22.110Z
Shell 1.7.9
Renderer 58.0.3029.110
Node 7.9.0
Architecture x64

and Rust (rls) version 0.3.2

When I write a simple program like this (cargo new test-rustfmt-vscode and replace lib.rs with these contents):

#[cfg(test)]
mod tests {
    #[test]
    fn it_works() {
        test();
        assert_eq!(2 + 2, 4);
    }
    type VeryLongName = i32;

    fn test(_a: VeryLongName,
            _b: VeryLongName,
            _c: VeryLongName,
            _d: VeryLongName,
            _e: VeryLongName) {
        ()
    }
}

and autoformat with cargo fmt nothing changes.

If I run Format Document in vscode it results in this:

#[cfg(test)]
mod tests {
    #[test]
    fn it_works() {
        test();
        assert_eq!(2 + 2, 4);
    }
    type VeryLongName = i32;

    fn test(
        _a: VeryLongName,
        _b: VeryLongName,
        _c: VeryLongName,
        _d: VeryLongName,
        _e: VeryLongName,
    ) {
        ()
    }
}

Did I miss some obvious setting or is this a reproducible bug?

Also probably related: #122 #132

It looks like you are using an old version of rustfmt locally. Perhaps you are using the rustfmt crate instead of rustfmt-nightly?

Yes, that was the problem 👍

Sorry to bother you with this. I did not know about these changes in the rust autoformatter.
