We currently have a student for training and had her learn Rust. After two weeks or so, she told me that she had a really hard time finding anything about Rust, and it became clear that she was really confused and thought Rust was some fringe technology that no one uses.
And yeah, no, search engines just got obliterated by LLM spam since the last time she had to learn a new technology. Seriously, I remember getting better results about Rust back in 2018, when it was really still relatively fringe...
One search that was memorable to me was looking for dimensional information on a T-slot. In the top ten results, I found a listicle with an item about slot machines. LLM spam and Google's relentless bullshit have poisoned the internet.
I've been into computers for over 20 years and I couldn't tell you what uses rust. I am aware of it, but I am completely unaware of how narrow or broadly it is used. I keep forgetting people aren't talking about the game.
I mean, to name a few projects off the top of my head:
Firefox
Android is migrating some of their internals.
The Linux kernel, Google Chrome, Thunderbird are preparing to use Rust.
Many Python programs now have Rust in there, because of the PyCrypto library.
Fish shell is in the middle of a RiiR.
I don't feel like there's a ton of big, mature projects yet, because of how relatively young Rust still is, but performance-critical or embedded software will be strongly considering Rust in the future.
And like C, Rust can be used to create libraries which can be called from practically any other programming language. I expect that to give it significant growth in the future.
Frankly, I do most of my searching these days directly on https://std.rs and https://docs.rs . But yeah, those are usually better as a reference than for learning.
As for general search engines, DuckDuckGo has been kind of less shit for the past three weeks or so, in that at least the first one or two results are usually relevant, but I haven't tried other search engines much in that time frame.
Another tip is to make use Clippy. Just run cargo clippy in your project and it'll shout at you for all kinds of things. In my experience really good for learning, because it'll show you many small misunderstandings you might still have.
