Macros are commonly presented as simple “text substitution” language features. But the way they’re implemented can change your experience using with them. The simplicity of a text-replacement-style implementation (sometimes referred to as C-style macros) can often lead to surprising and counter-intuitive results. As such, those feel simple to learn, but difficult to master and use safely. In Rust, however, macros work in a way that may be unfamiliar to many. They are recognized and processed during the compiler’s parsing phase. That can make them do some powerful things, but it also can make them a little hard to learn and understand initially. Since macros are a huge topic, there’s no way I’m going to be able to cover all of it in one article. So we’re only going to focus on a brief introduction to macros, as well as defining and using declarative macros. Updates: - 2026/10/08 - added an introduction covering what macros are, based on feedback from the Rust Users Forums.

This week, I released my first official open source crate - `typed-ident`! This crate is actually a small part of a few other projects that I’m working on. I’m not quite ready to share those other projects yet, but I figured instead of taking months to release a few big projects, I could break out this functionality, polish it up, and release that. After all, it eventually needed to be factored out, and it seemed like it wouldn’t be too difficult. That was the idea at least, but as I’m sure you can tell just looking at the crate (and reading this article), it didn’t quite go to plan. This article should be a fun ride - I learned a lot working on this crate, and maybe even if you don’t plan on using it you will too!

Though it’s taken me longer than expected, sigseis.dev is mostly done - with only a few remaining missing features and polish work. With this site being mostly finished, I thought it would be fun to write up a little article about some things you should check on your static sites! At least while it’s still fresh in my own mind. UPDATE: - 2026/08/04 - Added a section about “Optimizing Content Delivery”, dropped the “Sticky Headings” to be bonus content, and a small bit of text on `tabindex` in the accessibility section.

Today I’d like to talk a bit about how I like to organize my Rust projects. In particular, I’d like to talk about modules (you cannot talk about project organization without talking about modules). First, I’ll define what modules are, and give a brief explanation for how they work. After that, I’ll explain my recommended approach for organizing modules in Rust.
