我正在panic::catch_unwind惊慌失措:

use std::panic;

fn main() {
    let result = panic::catch_unwind(|| {
        panic!("test panic");
    });

    match result {
        Ok(res) => res,
        Err(_) => println!("caught panic!"),
    }
}

(游乐场)

这似乎工作得很好,但我仍然得到了恐慌的输出到stdout.我想这只打印出来:

caught panic!

代替

thread '<main>' panicked at 'test panic', <anon>:6
note: Run with `RUST_BACKTRACE=1` for a backtrace.
caught panic!
