这段程序会输出什么？

fn select<'a>(left: &'a str, right: &'a str, use_left: bool) -> &'a str {
    if use_left { left } else { right }
}

fn main() {
    let outer = String::from("east");

    {
        let inner = String::from("west");
        let result = select(&outer, &inner, true);
        println!("{result}");
    }
}
