So where do people go when they want to order custom stickers for their software project?

I think I fixed some ... but yeah ... I should check if there's a PR on my repo I guess, sometimes people fix them

Lately I've gotten kind of obsessed with the question of "how to manage cycles in Rust traits". I've begun to make real progress, so I decided to start blogging: smallcultfollowing.com/babysteps/bl...

I was thinking similarly, the ideal might be like “cargo add @cli” or something. Interesting question how it relates to namespacing.

nikomatsakis @nikomatsakis.com · 16/07/2026

Yeah, I think it’d be good to upstream it in some form eventually if the idea proves popular

This was in fact the inspiration.

New blog post describing an idea I’ve been kicking around called battery packs. Battery packs are a curated set of crates arranged around a common theme. Battery packs are meant to address one of the most common things I hear from new Rust adopters. smallcultfollowing.com/babysteps/bl...

Hmm actually… could just make an example that accesses each bit of the API I want to be public.

nikomatsakis @nikomatsakis.com · 11/06/2026

The problem is that I wind up with reachable pub that I don’t want but also I like to know when things are module private

010

nikomatsakis @nikomatsakis.com · 11/06/2026

(Well, almost. I’d be happy with something that makes pub into pub-crate unless I’ve explicitly told it not to, but it’s a start.)

120

nikomatsakis @nikomatsakis.com · 11/06/2026

But I also really like to have things be declared module-private or crate-private when they can be and I often find that gets 'out of date' when refactoring.

030

nikomatsakis @nikomatsakis.com · 11/06/2026

Do folks know of a lint to detect things that are "more public than they need to be"? I'd like to go so far as to document with `expect` or something the stuff my crate *intends* to expose to the outside world and get warnings about anything else.

That is a good way of explaining it— though it’s unclear if that should apply through super traits.

It is disabling the defaults.

The 'panic' around Lia Thomas was about creating a target people could point at while demanding exclusion. So much of what people “know” about Lia comes from manufactured outrage and years of misinformation repeated without context. We commissioned this comic to break down the actual story. 1/2

Cartoon of Lia Thomas with purple hair, smiling and holding a trophy, making a peace sign. Background features a trans flag and text about sports inclusivity.

A swimmer in the water with text overlay: "Lia's college swimming career began in 2017. Aged 18, she joined the University of Pennsylvania men's swimming team. Like most young athletes, her performances improved with age and experience."

Swimmer's in the water with text overlay: "Her overall best US ranking in the men's competition was 11th after placing 1st and 2nd in several events, including the 200 and 500 yard freestyle between 2017 and 2019."

A swimmer looking at the water in a red swimming costume and bathing cap, with a text overlay: "In 2019 she started HRT as part of her transition. Her performances dropped dramatically. She ranked 65th in the 500 yard free and 554th in the 200 yard free. Overall her US ranking dropped to 63rd."

Sad that RustWeek is over, and glad I got to spend the week with so many wonderful people. Next time you are delighted by how a Rust feature works, say thanks to all these folks who spent the week hashing out every possible edge case! Can't wait for next year's RustWeek! #rustweek #rustweek2026

This undercurrent within the #rustlang community (and others) has to stop. The attacks on people simply because they are using developer tools that make them productive is 100% out of line. I can respect the anti-LLM arguments, but let's agree to disagree, respect each other as humans, and move on.
