The State of Developer Ecosystem 2022 in Rust: Discover recent trends
The results of the Developer Ecosystem Survey 2022 are in!
Every year JetBrains conducts a survey to deepen our knowledge of the developer community and how it has changed over the past year.
Let’s dive into the report’s findings with the help of three members of the Rust community:
Work or hobby?
The share of developers using Rust for work grew from 16% in 2020 and 2021 to 18% in 2022.
Florian: “I’ve noticed that although Rust is growing, the relative numbers here are staying the same. That’s good! It means the number of Rust hobbyists is increasing and they can turn professional at a good rate. Employers take note: If you look beyond people with ‘X years of professional Rust experience’, you’ll find a big hiring pool of people willing to switch from their current jobs.”
Aleksey: “Anecdotally, Rust did transition from ‘a weird new language’ to ‘it wouldn’t be insane to put this into production’ a couple of years ago, so growth here is expected, and very welcome.”
Experienced Rustaceans are hard to find
According to the survey, 24% of Rustaceans have used Rust for more than one year. This is an increase of 4 percentage points from last year, but it’s still not easy to find experienced Rust developers.
Andre: “People who have used Rust in the past are by and large still using it. The relative share of newcomers has been nearly constant, showing a healthy organic growth pattern. The share of senior Rustaceans has grown, which is good news for employers seeking them.”
Florian: “Rust is a young language, so it’s hard to find people with years of experience. For that reason, managers adopting Rust should budget for training and other forms of education and support for their teams. Also, consider that someone who has programmed for decades can adopt a new programming language rather quickly with help.”
Rust and other languages
Andre: “Roughly half of the responders are polyglot programmers, using another language alongside Rust. It looks like the percentages roughly mirror current popularity. As they say, the perfect tool is often the one you already hold.”
The share of developers using
dbg! macros decreased from 60% to 55%, while the usage of UI debugging in IDEs increased from 23% to 27% since last year.
Andre: “More people use a debugger now, likely because support has improved since last year. The
dbg! macro still unsurprisingly takes the cake, as a quick and easy way to get insight about the runtime state. And let’s not forget that, with Rust being as picky as it is, applications often don’t need debugging in the first place.”
Aleksey: “Debuggers are as much of a pain as ever. I myself use
eprintln! (via pd snippet in my IDE), but I miss great debuggers from my time with Kotlin.”
The most popular profiling tool used by Rust developers is perf, but the vast majority of Rusteceans – 82% – don’t use profiling tools at all.
Florian: “It’s amazing – but also not surprising – that in a language that many people use for speed, performance measurement isn’t a common practice. My theory is that performance tooling is inaccessible and differs based on platform.”
Aleksey: “That’s squarely the toolchain’s fault! All the tools listed here are impossibly fiddly to use. If you do profiling full-time (so, a perf engineer on a big project, a-la nnethercote), you can invest time and effort into learning all the perf flags. If, however, you want to spend only a fraction of time doing perf investigation, the learning curve is very unfriendly. I wish Rust took a page from Go’s book, which has
pprof.StartCPUProfile as part of the toolchain. This is going to require a huge effort, though.”
Rust for CLI
Developers use Rust mostly for building CLI tools, systems programming, and web development.
Andre: “CLI tools have proven to be a niche area where Rust shines. Last year, almost half of developers were developing them. What’s also interesting is that, while blockchain companies often proudly boast that they use Rust, only 6% of respondents actually work in that space. This is either a case of outsized hype and marketing or the few Rustaceans who work in blockchains are very effective developers. Or both.”
Florian: “Given that the public perception of Rust is that there are a lot of Rust jobs in the blockchain industry, I’m quite surprised to see this option below even embedded and academic use.”
Unsurprisingly, Linux takes first place as the primary Rust target platform. The integration of Rust into the Linux world continues as initial Rust support was merged into the Linux kernel in October.
Andre: “Linux reigns supreme, though Windows has made headway. I think this may be due to Microsoft investing in Rust, combined with the fact that Linux users are often early adopters and the growing community now has more conservative users, who tend to use the OS their PC came with.”
Florian: “Another tiny surprise for me – I would have placed WebAssembly somewhere around embedded use. Once again, this shows how important polling is.”
The share of developers using rust-analyzer has increased from 25% to 45%. IntelliJ Rust is used by 42% of developers, compared to 47% last year.
Aleksey: “Huge growth for rust-analyzer! Not surprising, given that the rust-analyzer project recently became a part of the wider Rust organization, and the Rust Language Server (RLS) has been deprecated in favor of rust-analyzer. I am personally quite happy that a lot of folks use advanced IDEs for Rust, and that there’s healthy competition and collaboration between IntelliJ Rust and rust-analyzer!”
Andre: “rust-analyzer has made major headway, now being the official LSP implementation for Rust. IntelliJ Rust has stayed very strong, too. Having worked with both, I still switch between them every now and then. Two fine pieces of engineering. Kudos!”
