New Rustacean – learning the Rust programming language

On the responsibilities and opportunities we have to help others with our knowledge and abilities. 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!

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! The Copy and Clone traits, plus the Cow type, give us everything we need!

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.

Avoiding burnout by taking it a little easier. Sometimes, the way a podcast stays in existence is by coming out less often.

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. As was the case with e016, the code samples have little to say in their documentation; reading the code will be necessary for seeing the ideas.

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!

Raph Levien on using Rust to build the Xi editor Notes Chris chats with Raph Levien about his background in software development, what attracted him to Rust, and how he’s using Rust to build the Xi Editor, a project which aims to be the fastest text editor out there, with native user interfaces and a Rust text engine.

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.
