CYSK: RLS
April 18, 2017 18:17 - 11 minutes - 10.6 MBWhere 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! Links Rust Language Service repo blog posts announcement alpha 2 rel...
e020: Putting code in its place
April 01, 2017 18:38 - 20 minutes - 18.7 MBHow 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 i...

March 19, 2017 15:00 - 13 minutes - 12.4 MBOn 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!

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! Links underhanded.rs The typess std::marker::Copy "Copy t...

January 31, 2017 23:32 - 17 minutes - 14 MBThree traits which are essential for designing good, Rustic APIs.

August 20, 2016 16:15 - 11 minutes - 7.89 MBBuilding (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.

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 agai...

June 18, 2016 00:07 - 20 minutes - 7.94 MBBox, 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.

Bonus 5: Better than open-source contributions
May 10, 2016 01:47 - 11 minutes - 4.41 MBSome 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.

e013: Staying alive
April 04, 2016 23:52 - 17 minutes - 7.17 MBReasoning 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.

March 21, 2016 11:00 - 16 minutes - 6.88 MBWhat 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.

Corrigenda Sean noted he could be wrong about IEnumerable<T> not having a Sum method in C♯, and post-show research indicated that he was (it's possible it was added after he had stopped doing .NET work, of course).

e010: Macros rule!
January 18, 2016 15:25 - 16 minutes - 6.78 MBMacros rule! Notes Because of the way macros are exported—before name resolution on crates occurs—the documentation for the macros defined in the source for this episode occurs in the Macros section of the show_notes crate documentation, rather than within the documentation for this module. (See the Rust Book discussion of documenting macros for details.) Even so, the source is still in this module; see the implementations for details.

e009: Composing a Rustic tune
January 09, 2016 21:00 - 17 minutes - 6.68 MBNotes Last time, we looked at generics and traits at a high level. This time, we dig deeper on traits, looking specifically at std::iter::Iterator as an example of a powerful trait that can be composed across types, and then at how we might compose multiple traits on a single type. We also talk about the syntax for traits, the use of marker traits, some of the things you can’t presently do with traits, and even just a smidge about the future of traits in Rust. All that in less than 20 minu...
e008: Just like something else
December 27, 2015 16:19 - 17 minutes - 6.55 MBNotes In this episode we cover—at a very high level—two more fundamental concepts in Rust programming: generics and traits. Generics gives us the abilitty to write types and functions which can be used with more than one type. Traits give us the ability to specify behavior which can be implemented for more than one type. The combination gives us powerful tools for higher-level programming constructs in Rust. Comments on source code Now that we have a handle on how tests work, we’ll use t...

December 13, 2015 17:38 - 18 minutes - 7.08 MBNotes All about testing in Rust! In order, we take a look at: Why you need tests. Unit tests in other (dynamically-typed) languages vs. in Rust. How to write unit tests in Rust. How and why to write integration tests in Rust. How and why to use benchmarks in Rust. The detailed code samples for this episode are heavy on showing; because of the nature of test functions, you will be best off just reading the source rather than leaning heavily on the descriptions generated by rustdoc.

e006: Modularize this!
November 16, 2015 15:36 - 18 minutes - 8.87 MBNotes Today, we are talking about modules, packages, and APIs in Rust. Taking a bit of a breather after some pretty hard material the last few weeks. For reference, the Rust book section on Crates and Modules will be very helpful. Corrigenda I accidentally called this episode 5, instead of episode 6. Whoops. Just before the 15:00 mark, while discussing libraries, I referred to “e006.md” when I meant to say “e006.rs”. Slips of the tongue inspired by the fact that Rust (delightfully) uses...

November 08, 2015 20:15 - 18 minutes - 9.11 MBAllocate it where? Subject: Returning functions from other functions, and thinking about the stack, the heap, and reference types. MP3 Notes This episode, we look at returning functions from other functions, and as part of that discuss some basics about the stack and the heap—and why we need to care about them for returning functions. The functions themselves are not especially interesting; they just show you the basic form you use to return functions from other functions, and how to th...

Notes Today’s episode discusses, in order: Enumerated types, with an eye to the difference between structs and enums, and to the differences between enums in C and in Rust. Pattern matching, with a focus on using them with enumerated types and some discussion about how they differ from switch blocks in C-like languages. Using the Option and Result enumerated types with pattern matching to pro...
