Hello, Rustaceans!
The Rust Survey Team is excited to share the results of our 2024 survey on the Rust Programming language, conducted between December 5, 2024 and December 23, 2024. As in previous years, the 2024 State of Rust Survey was focused on gathering insights and feedback from Rust users, and all those who are interested in the future of Rust more generally.
This ninth edition of the survey surfaced new insights and learning opportunities straight from the global Rust language community, which we will summarize below. In addition to this blog post, we have also prepared a report containing charts with aggregated results of all questions in the survey.
Our sincerest thanks to every community member who took the time to express their opinions and experiences with Rust over the past year. Your participation will help us make Rust better for everyone.
There's a lot of data to go through, so strap in and enjoy!
Participation
| Survey | Started | Completed | Completion rate | Views |
|---|---|---|---|---|
| 2023 | 11 950 | 9 710 | 82.2% | 16 028 |
| 2024 | 9 450 | 7 310 | 77.4% | 13 564 |
As shown above, in 2024, we have received fewer survey views than in the previous year. This was likely caused simply by the fact that the survey ran only for two weeks, while in the previous year it ran for almost a month. However, the completion rate has also dropped, which seems to suggest that the survey might be a bit too long. We will take this into consideration for the next edition of the survey.
Community
The State of Rust survey not only gives us excellent insight into how many Rust users around the world are using and experiencing the language but also gives us insight into the makeup of our global community. This information gives us a sense of where the language is being used and where access gaps might exist for us to address over time. We hope that this data and our related analysis help further important discussions about how we can continue to prioritize global access and inclusivity in the Rust community.
Same as every year, we asked our respondents in which country they live in. The top 10 countries represented were, in order: United States (22%), Germany (14%), United Kingdom (6%), France (6%), China (5%), Canada (3%), Netherlands (3%), Russia (3%), Australia (2%), and Sweden (2%). We are happy to see that Rust is enjoyed by users from all around the world! You can try to find your country in the chart below:
We also asked whether respondents consider themselves members of a marginalized community. Out of those who answered, 74.5% selected no, 15.5% selected yes, and 10% preferred not to say.
We have asked the group that selected “yes” which specific groups they identified as being a member of. The majority of those who consider themselves a member of an underrepresented or marginalized group in technology identify as lesbian, gay, bisexual, or otherwise non-heterosexual. The second most selected option was neurodivergent at 46% followed by trans at 35%.
Each year, we must acknowledge the diversity, equity, and inclusivity (DEI) related gaps in the Rust community and open source as a whole. We believe that excellent work is underway at the Rust Foundation to advance global access to Rust community gatherings and distribute grants to a diverse pool of maintainers each cycle, which you can learn more about here. Even so, global inclusion and access is just one element of DEI, and the survey working group will continue to advocate for progress in this domain.
Rust usage
The number of respondents that self-identify as a Rust user was quite similar to last year, around 92%. This high number is not surprising, since we primarily target existing Rust developers with this survey.
Similarly as last year, around 31% of those who did not identify as Rust users cited the perception of difficulty as the primary reason for not using Rust. The most common reason for not using Rust was that the respondents simply haven’t had the chance to try it yet.
Of the former Rust users who participated in the 2024 survey, 36% cited factors outside their control as a reason why they no longer use Rust, which is a 10pp decrease from last year. This year, we also asked respondents if they would consider using Rust again if an opportunity comes up, which turns out to be true for a large fraction of the respondents (63%). That is good to hear!
Closed answers marked with N/A were not present in the previous version(s) of the survey.
Those not using Rust anymore told us that it is because they don't really need it (or the goals of their company changed) or because it was not the right tool for the job. A few reported being overwhelmed by the language or its ecosystem in general or that switching to or introducing Rust would have been too expensive in terms of human effort.
Of those who used Rust in 2024, 53% did so on a daily (or nearly daily) basis — an increase of 4pp from the previous year. We can observe an upward trend in the frequency of Rust usage over the past few years, which suggests that Rust is being increasingly used at work. This is also confirmed by other answers mentioned in the Rust at Work section later below.
Rust expertise is also continually increasing amongst our respondents! 20% of respondents can write (only) simple programs in Rust (a decrease of 3pp from 2023), while 53% consider themselves productive using Rust — up from 47% in 2023. While the survey is just one tool to measure the changes in Rust expertise overall, these numbers are heartening as they represent knowledge growth for many Rustaceans returning to the survey year over year.
Unsurprisingly, the most popular version of Rust is latest stable, either the most recent one or whichever comes with the users' Linux distribution. Almost a third of users also use the latest nightly release, due to various reasons (see below). However, it seems that the beta toolchain is not used much, which is a bit unfortunate. We would like to encourage Rust users to use the beta toolchain more (e.g. in CI environments) to help test soon-to-be stabilized versions of Rust.
People that use the nightly toolchain mostly do it to gain access to specific unstable language features. Several users have also mentioned that rustfmt works better for them on nightly or that they use the nightly compiler because of faster compilation times.
Learning Rust
To use Rust, programmers first have to learn it, so we are always interested in finding out how do they approach that. Based on the survey results, it seems that most users learn from Rust documentation and also from The Rust Programming Language book, which has been a favourite learning resource of new Rustaceans for a long time. Many people also seem to learn by reading the source code of Rust crates. The fact that both the documentation and source code of tens of thousands of Rust crates is available on docs.rs and GitHub makes this easier.
In terms of answers belonging to the "Other" category, they can be clustered into three categories: people using LLM (large language model) assistants (Copilot, ChatGPT, Claude, etc.), reading the official Rust forums (Discord, URLO) or being mentored while contributing to Rust projects. We would like to extend a big thank you to those making our spaces friendly and welcoming for newcomers, as it is important work and it pays off. Interestingly, a non-trivial number of people "learned by doing" and used rustc error messages and clippy as a guide, which is a good indicator of the quality of Rust diagnostics.
In terms of formal education, it seems that Rust has not yet penetrated university curriculums, as this is typically a very slowly moving area. Only a very small number of respondents (around 3%) have taken a university Rust course or used university learning materials.
Programming environment
In terms of operating systems used by Rustaceans, Linux was the most popular choice, and it seems that it is getting increasingly popular year after year. It is followed by macOS and Windows, which have a very similar share of usage.
As you can see in the wordcloud, there are also a few users that prefer Arch, btw.
Rust programmers target a diverse set of platforms with their Rust programs. We saw a slight uptick in users targeting embedded and mobile platforms, but otherwise the distribution of platforms stayed mostly the same as last year. Since the WebAssembly target is quite diverse, we have split it into two separate categories this time. Based on the results it is clear that when using WebAssembly, it is mostly in the context of browsers (23%) rather than other use-cases (7%).
We cannot of course forget the favourite topic of many programmers: which IDE (developer environment) they use. Although Visual Studio Code still remains the most popular option, its share has dropped by 5pp this year. On the other hand, the Zed editor seems to have gained considerable traction recently. The small percentage of those who selected "Other" are using a wide range of different tools: from CursorAI to classics like Kate or Notepad++. Special mention to the 3 people using "ed", that's quite an achievement.
You can also take a look at the linked wordcloud that summarizes open answers to this question (the "Other" category), to see what other editors are also popular.
Rust at Work
We were excited to see that more and more people use Rust at work for the majority of their coding, 38% vs 34% from last year. There is a clear upward trend in this metric over the past few years.
The usage of Rust within companies also seems to be rising, as 45% of respondents answered that their organisation makes non-trivial use of Rust, which is a 7pp increase from 2023.
Once again, the top reason employers of our survey respondents invested in Rust was the ability to build relatively correct and bug-free software. The second most popular reason was Rust’s performance characteristics. 21% of respondents that use Rust at work do so because they already know it, and it's thus their default choice, an uptick of 5pp from 2023. This seems to suggest that Rust is becoming one of the baseline languages of choice for more and more companies.
Similarly to the previous year, a large percentage of respondents (82%) report that Rust helped their company achieve its goals. In general, it seems that programmers and companies are quite happy with their usage of Rust, which is great!
In terms of technology domains, the situation is quite similar to the previous year. Rust seems to be especially popular for creating server backends, web and networking services and cloud technologies. It also seems to be gaining more traction for embedded use-cases.
You can scroll the chart to the right to see more domains. Note that the Automotive domain was not offered as a closed answer in the 2023 survey (it was merely entered through open answers), which might explain the large jump.
It is exciting to see the continued growth of professional Rust usage and the confidence so many users feel in its performance, control, security and safety, enjoyability, and more!
Challenges
As always, one of the main goals of the State of Rust survey is to shed light on challenges, concerns, and priorities on Rustaceans’ minds over the past year.
We have asked our users about aspects of Rust that limit their productivity. Perhaps unsurprisingly, slow compilation was at the top of the list, as it seems to be a perennial concern of Rust users. As always, there are efforts underway to improve the speed of the compiler, such as enabling the parallel frontend or switching to a faster linker by default. We invite you to test these improvements and let us know if you encounter any issues.
Other challenges included subpar support for debugging Rust and high disk usage of Rust compiler artifacts. On the other hand, most Rust users seem to be very happy with its runtime performance, the correctness and stability of the compiler and also Rust's documentation.
In terms of specific unstable (or missing) features that Rust users want to be stabilized (or implemented), the most desired ones were async closures and if/let while chains. Well, we have good news! Async closures will be stabilized in the next version of Rust (1.85), and if/let while chains will hopefully follow soon after, once Edition 2024 is released (which will also happen in Rust 1.85).
Other coveted features are generators (both sync and async) and more powerful generic const expressions. You can follow the Rust Project Goals to track the progress of these (and other) features.
In the open answers to this question, people were really helpful and tried hard to describe the most notable issues limiting their productivity. We have seen mentions of struggles with async programming (an all-time favourite), debuggability of errors (which people generally love, but they are not perfect for everyone) or Rust tooling being slow or resource intensive (rust-analyzer and rustfmt). Some users also want a better IDE story and improved interoperability with other languages.
This year, we have also included a new question about the speed of Rust's evolution. While most people seem to be content with the status quo, more than a quarter of people who responded to this question would like Rust to stabilize and/or add features more quickly, and only 7% of respondents would prefer Rust to slow down or completely stop adding new features.
Interestingly, when we asked respondents about their main worries for the future of Rust, one of the top answers remained the worry that Rust will become too complex. This seems to be in contrast with the answers to the previous question. Perhaps Rust users still seem to consider the complexity of Rust to be manageable, but they worry that one day it might become too much.
We are happy to see that the amount of respondents concerned about Rust Project governance and lacking support of the Rust Foundation has dropped by about 6pp from 2023.
Looking ahead
Each year, the results of the State of Rust survey help reveal the areas that need improvement in many areas across the Rust Project and ecosystem, as well as the aspects that are working well for our community.
If you have any suggestions for the Rust Annual survey, please let us know!
We are immensely grateful to those who participated in the 2024 State of Rust Survey and facilitated its creation. While there are always challenges associated with developing and maintaining a programming language, this year we were pleased to see a high level of survey participation and candid feedback that will truly help us make Rust work better for everyone.
