Also, a nitpick:
> One line of unsafe (std::mem::transmute::<u8>() -> i8)
You don't need unsafe for this, you can do that with an `as` cast.
Edit: Jesus kids, learn a little chill it was a joke. Someone didn’t like this so much they went through and downvoted all my other posts they could. Wow... that’s real serious.
Edit: yeah, “Casting between two integers of the same size (e.g. i32 -> u32) is a no-op” (https://doc.rust-lang.org/reference/expressions/operator-exp...)
In the Rust definition of safety (mutable xor shared, no data races, memory safety, etc), treating the bits of a u8 as an i8 is safe and can be done with an `as` cast.
