It’s worth noting that a decent percentage of users who use nightly do so out of habit because “nightly is stable enough”. The next largest reason for nightly was const generics, but with a minimal version of const generics reaching stable, we should see less of a reliance on nightly for this feature. When asked why people are using nightly the largest reason was to use the Rocket web framework which has announced it will work on the stable version of Rust in its next release. In addition to improvements in the IDE experience, the number of users who are relying on a nightly compiler at least part of the time continues to drop - down to 28% compared with last year’s 30.5% with only 8.7% of respondents saying they use nightly exclusively. Nearly 3/4ths of all respondents noted that they saw at least some improvement in the IDE story, but users of rust-analyzer and IntelliJ were especially happy with 47% of rust-analyzer users noting “a lot of improvement” while 40% of IntelliJ users said the same. While this work is not nearly completed, respondents have noted that the stability of Rust in general has been improving.įirst, we’d like to make a shout out to the rust-analyzer and IntelliJ Rust plugin projects which both enjoy relatively happy user bases.
Rust in 2020 has largely been about cleaning up and stabilizing features and initiatives that were already under way. While Rust itself has always had a strong stability guarantee, stability often means more than just ensuring users’ code doesn’t break when compiled with a new version of the compiler. When asked why they had stopped using Rust, the largest group (35%) said they just hadn’t learned it yet (presumably from lack of time), followed by those whose company was not using Rust (34%) and those who said switching to Rust would “slow them down” compared to their current language of choice (19%). Here's the distribution of languages across the responses:Ĩ3.0% of respondents said they used Rust (an all time high) while 7% said they had used Rust in the past but no longer do. The survey was available in 14 different languages and had a record 8,323 total responses. Without further ado, let’s dive into the analysis! Survey Audience We’d like to thank everyone who participated in this year’s survey with a special shout-out to those who helped translate non-English responses.
Another year has passed, and with it comes another annual Rust survey analysis! The survey was conducted in the second half of September 2020 over a two-week period.
