rust-beginning-of-defun can not find real function

[Dushistov]

As described in comment of kwrooijen/cargo.el#41 I have problem with rust-beginning-of-defun.

With rust code in literal string rust-beginning-of-defun works in wrong way:

fn test1() {
    let s = r#"
fn test2();
"#;<CURSOR_HERE>
}

M-x rust-beginning-of-defun jumps to test2 not to test1 as expected.
