Crate of the Week

This week, Crate of the Week is Itertools. Thanks go to llogiq for the suggestion. In his own words:

So today I'll write about Itertools. Because iterators in Rust are awesome, and this crates makes them even awesome-r. If you want to do something with iterators that seems to be slightly impossible using the std APIs, chances are Itertools already implements a way that is both fast and elegant. Knowing your itertools APIs will level up your Rust-fu. For a (very small and simple) example, haven't you wished to zip two iterators, but don't stop iteration after the shorter iterator has run out? With Itertools you can just say x.zip_longest(y) and get an iterator of EitherOrBoth<X, Y> .
