When writing codecs in Rust I found the Iterator trait (and all its provided methods) to be very useful for avoiding panics relating to out of bounds indexing into arrays. It also tends to generate very efficient code since bounds checks are done on the order of once per loop rather than once per loop iteration. And then there is the powerful itertools crate that gives you even more capabilities. Highly recommended!
