Example of panic! inside a thread in Rust

panic-thread.rs

fn main() {
    let x = std::thread::spawn(|| {
        std::thread::sleep(std::time::Duration::from_secs(1));
        panic!("I am crashing!");
    })
    .join();
    println!("This result should not be visible! {x:?}");
}

/// This program's output:
///
/// thread '<unnamed>' panicked at src/main.rs:4:9:
/// I am crashing!
/// note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
/// This result should not be visible! Err(Any { .. })
