The Many Kinds of Code Reuse in Rust (This article is written against Rust 1.7 stable) Rust has a lot of stuff in its type system. As far as I'm concerned, almost all of the complexity is dedicated to expressing programs generically. And people are still clamouring for more! I always have trouble getting the most advanced parts straight, so this post is basically a "note to self". That said, I lik

Learning Rust With Entirely Too Many Linked Lists Got any issues or want to check out all the final code at once? Everything's on Github! I fairly frequently get asked how to implement a linked list in Rust. The answer honestly depends on what your requirements are, and it's obviously not super easy to answer the question on the spot. As such I've decided to write this book to comprehensively answ

Pre-Pooping Your Pants With Rust Alexis Beingessner - April 27, 2015 Leakpocalypse Much existential anguish and ennui was recently triggered by Rust Issue #24292: std::thread::JoinGuard (and scoped) are unsound because of reference cycles. If you feel like you're sufficiently familiar with Leakpocalypse 2k15, feel free to skip to the next section. If you've been thoroughly stalking all my online i

Rust Collections Case Study: BTreeMap Alexis Beingessner This is the third entry in a series on implementing collections in the Rust programming language. The full list of entries can be found here. In my previous two posts I talked a lot about some high-level patterns and issues that make implementing collections in Rust an interesting problem. Today I'd like to really dig into one of my two favo

Rust, Generics, and Collections Alexis Beingessner Last time I wrote about how Rust's notion of lifetimes lets us write and use collections much in the same way that we would in other languages, while protecting us from many of the classic mistakes you can make when working with collections. Things like iterator invalidation and mutating a collection while holding an internal reference just can't
