pub fn take_hook() -> Box<dyn Fn(&PanicInfo<'_>) + Sync + Send + 'static>ⓘNotable traits for Box<I, A>impl<I, A> Iterator for Box<I, A> where    I: Iterator + ?Sized,    A: Allocator,     type Item = <I as Iterator>::Item;impl<F, A> Future for Box<F, A> where    F: Future + Unpin + ?Sized,    A: Allocator + 'static,     type Output = <F as Future>::Output;impl<R: Read + ?Sized> Read for Box<R>impl<W: Write + ?Sized> Write for Box<W>

    println!("Custom panic hook");
}));
