A Rust macro xkcd_unreachable!() inspired by xkcd 2200
use xkcd_unreachable::xkcd_unreachable;
fn foo(x: Option<i32>) {
match x {
Some(n) if n >= 0 => println!("Some(Non-negative)"),
Some(n) if n < 0 => println!("Some(Negative)"),
Some(_) => xkcd_unreachable!(),
None => println!("None")
}
}⚠ ERROR
If you're seeing this, the code is in what
I thought was an unreachable state.
I could give you advice for what to do.
But honestly, why should you trust me?
I clearly screwed this up. I'm writing a
message that should never appear, yet
I know it will probably appear someday.
On a deep level, I know I'm not
up to this task. I'm so sorry.
