Hey folks,

This is driving me absolutely nuts. This of course doesn’t compile:

impl Display for TestResult {
    fn fmt(&self, f: &mut Formatter<'\_>) -> std::fmt::Result {
        writeln!(f, "{}", self.main_line())

        if let Some(detail_line) = self.detail_line() {
            writeln!(f, "{}", detail_line)
        }
    }
}

How would I do this properly?

Thanks!
