Description
If you run rustfmt and it errors out, it currently just "beeps" and suggests you switch over to *rustfmt*. I think this should be treated like a failed compilation; we should split the frame into two windows, show the errors, and let you use M-x next-error to view them.
Example 1, which errors because it doesn't parse:
fn main() {
let x &'static str = "aaa";
}Example 2, undefined module:
mod a;
fn main() {
let x: &'static str = "aaa";
}Example 3, long lines:
fn main() {
let x:
&'static str = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
}
