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.

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 them to validate the behavior of our code going forward. This is great: we can show that the tests do what we think. To today’s point, though: we actually know even apart from whether the tests _run_ successfully that these generic functions and the associated traits are behaving as we want.

(The descriptions are still _there_, but they’re much less useful than they have been in previous episodes.) In particular, the test module here is excluded because of the use of the #[cfg(test)] attribute marker on it. Because we are using the feature-gated benchmarking functionality, the show notes “library” can now only be compiled with the Rust nightly (as of 1.5, the version current as this episode is produced). One thing that isn’t necessarily obvious from reading the test documentation in the Rust book and Rust reference: the extern crate test statement needs to be not in this module, but at the module (lib.rs) which defines the library/crate; in this case, show_notes/lib.rs.

Per [Rust RFC 505][1], the preferred approach is always to use the &quot;following&quot; form (`///`) rather than the &quot;containing&quot; form (), except for module-level docs like these. (I will be following RFC 505 throughout.)

You can skip it if you just want to start with something more technical, but I thought listeners might want to know a little about the origins of the show and my own background, so that’s what you get today. Next time, we’ll be tackling the rustic command in some detail. This is an almost-empty module: we aren’t doing any fun code samples yet. I included the standard “Hello, world!” example, because how could I not? However, at some point in the future, there will be much more detailed code samples available: * in the GitHub repository for the show * in the show notes attached to each episode Hopefully, the result will be a pretty helpful bunch of side content along with the audio of the podcast itself. 17:11
