odd_is_odd

A very (not) safe library to check if a number is odd. Abuses the same bugs and tricks in cve-rs to transmute the given i8 to a bool without using unsafe.

This relies on a compiler bug, almost certainly doesn't work on all platforms, and is possibly the least reasonable is_odd function you could imagine.

Example:

use odd_is_odd::is_odd;
fn main() {
    if (is_odd(69)) {
        println!("on our way to hundreds of thousands of downloads a week!");
    } else {
        println!("who could have guessed, the sketchy library is sketchy");
        assert!(false);
    }
}
