Structured Exception Handling

Shitty attempt to get SEH working in Rust on Windows.

This works by handling the SEH code in C++ and calling that from Rust, I'm sure this is in violation of various standards but it works!

Probably don't want to mix this with panics. Nasal demons and all that.

use wineh::unsafe_seh;

#[inline(never)]
fn crash(a: i32, b: i32) -> i32 { a / b }

fn main() {
	unsafe_seh! {
		__try {
			println!("__try");
			let i = crash(0, 0);
			println!("{}", i);
		}
		__except(1) {
			println!("__except");
		}
	}
}
