Shouldn't these cloned be copied?
There was a problem hiding this comment.
I thought so too, but apparently cloned() on an iterator changes an iterator over &T to T per the docs so what is really happening here is this is just converting the &u8 to a hard u8 for comparison.
Here is the implementation of clone() for all primitive types source and it's marked #[always_inline] so it's basically just a dereference...
fn clone(&self) -> Self {
*self
}
