Since Rust people are reading this.

I find myself wanting to walk an iterator pairwise regularly for stuff like this and I'm using:

    for (cur, next) in (& vec).iter().zip(vec.iter().skip(1)) {
        encoded_data.push(cur);
        if cur == 0xff && next == 0x00 {
            // ...
        }
    }

Is there a better way to write this? What I'd really like is the equivalent to Clojure's partition[1]. I know that the stdlib has windows `(partition n (dec n) seq)` and chunks `(partition n n seq)` implemented on slices but I usually want this on iterators for the lookahead-like behavior shown here.
