Where the RLS came from, what it can do, and how you can start using it today! Notes One major ergonomic improvement to developing in Rust in 2017 is coming via the Rust Language Service: an initiative that lets us share a common core of functionality between every editor – from Vim to VS Code and everything in between. In today's episode, I give some background on it and talk about how you can start using it today!

How do we organize code in Rust? Where do we break it apart into modules or crates, and why? Notes Structuring code in a language like Rust can seem a bit more ambiguous than doing the same in a language with classes to attach all our functionality to, but in practice, the concerns are much the same: modules are namespaces, and we group by responsibility. In today's episode, I talk through that philosophy (and give some comparisons to other languages), and then look at what it looks like in practice! Links Learning Rust Modules, by Jeff Walker, has a nice comparison of C# namespaces and Rust modules. The commit on Lightning inspired by this episode.

On the responsibilities and opportunities we have to help others with our knowledge and abilities. Notes Many of us have been very blessed with opportunities and support as we learn software. We should go out of our way to share with others in kind. Today, my focus is on teaching, but there are lots of ways to "give back." And I'd love to hear your thoughts and things you're doing in that vein! Links Julia Evans keyof and Mapped Types in TypeScript 2.1 -- the blog post I mentioned writing a few months ago.

code{white-space: pre;} The final pieces of the story for (single-threaded) memory management in Rust. Notes Sometimes, we actually do need to copy types. Wouldn't it be nice if Rust gave us a convenient way to do that when it's convenient, or when the cost is low enough that the ergonomic tradeoffs are worth it? Well, perhaps unsurprisingly, it does!

Three traits which are essential for designing good, Rustic APIs. Notes Borrow, AsRef, and Deref are a little complicated, but they're well-worth understanding. Together, they give you tools for dealing with everything from HashMap and friends to conversions involving smart pointer types to easily using String and str or Vec and slice together.

Building (and celebrating) all the little, not-so-glorious pieces of the Rust ecosystem. Notes We love the Rust compiler team. But there’s more to the Rust community, and more required for Rust to be as great as it can be, than just the language itself. We need to celebrate other libraries, and even the small ones, just as much (and maybe more) than changes to the language. We need to dig in and work on building the whole ecosystem.

A deep dive on references and pointers in Rust. Notes By listener request, today we look at the syntax and semantics of referencing and dereferencing and the corresponding & and * operators.

Digging deeper on smart pointers and mutability with Cell and RefCell. Notes What are the Cell and RefCell types, and when should we use them? Today, we follow up both the detailed discussion of smart pointers in e015 and the closely related discussion in Interview 2 with Raph Levien, and look at two types you need to have a good idea how to deal with if you want to use these smart pointer types more ergonomically—that is, how to use them without feeling like you’re beating your head against a wall!

Box, String, Vec, Rc, and Arc have this in common: they’re not dumb. This episode, we take a close look at smart pointer types—from a few we’ve already talked about, like Box, Vec, and String, to some new ones, like Rc and Arc. What smart pointers are, and what makes them ‘smart’. Why we want or need smart pointers. A bit about Box. A lot more about Rc and Arc.
