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.

Some things matter more than contributing to open-source software in your free time. A lot more. It’s trendy to ask for open-source work as evidence of your interest in tech and commitment to software development. Trendy and completely wrong. Companies should not demand open-source contributions from their employees, and beyond that, should learn to recognize that profit is not the most valuable thing in the world. People are.

Strings &strs and Vecs and slices (and Unicode) – oh, my! Notes This episode, I take a deep dive on strings in Rust, looking at the differences between String and &str, discussing Unicode a bit, and then expanding the discussion to think about how these types relate to the types they’re built on (like Vec).

Just how good Rust is, and how you can learn it even if you’re busy. Notes Sometimes life goes crazy and I don’t have time to do all the technical writing required for a full episode, but I can’t get Rust off my mind, so I record an episode like this one. Where I talk a bit about how versatile Rust is and suggest some surprising ways you might be able to use it.

Reasoning about and using lifetimes in Rust (and why we need them) Notes Lifetimes are our way of reasoning about how long a given piece of data is available and safe to use in Rust. The reason we don't have the dangling pointer problem is that we do have lifetimes instead. They're not magic, they're just a bit of semantics and syntax that let us specify the rules for how long any given item lives, and how long references to data must be valid.

What it means to be an expression-oriented language, and how that works out in Rust. Notes Rust is an expression-oriented language. What does that mean, and how does it play out in Rust? We look at if and match blocks, discuss looping constructs, and examine functions, and then widen out to discuss how having an expression-oriented language can change the way we think about programming.

Type systems: strong vs. weak, dynamic vs. static, and degrees of expressivity. Notes Talking about type systems! A broad and wide-ranging discussion about type systems in general, with specific examples from languages like PHP, JavaScript, Python, C, C++, Java, C♯, Haskell, and Rust! * What is a type system? * What are the kinds of things we get out of type systems? * What are the tradeoffs with different type systems? * What is Rust’s type system like? * What is especially attractive about Rust’s type system? A comment on the C integer/character string addition example: what’s actually happening there is that the character string is an array “under the covers,” and as such has an address. C silently switches to using the memory address, which is of course just an integer, when you try to add the two together. As I said on the show: the result is nonsense (unless you’re using this as a way of operating on memory addresses), but it’s compellable nonsense. In a stricter and stronger type system, memory addresses and normal numbers shouldn’t be addable!
