Rust 2021 – Looking Back and Forth

2021 was a great year for Rust. The language got more powerful. The standard library gained a good number of new functions and a lot of improvements on the existing ones. The error messages were tweaked and tweaked again. The compiler got faster still, despite at last enabling noalias information by default.

Also incremental compilation the default again after being backed out due to soundness problems. We got a new experimental gcc-based backend, and another gcc-based implementation (both are work in progress for now). Clippy gained a number of lints and lost a lot of false positives in turn. Rust is getting into the Linux kernel, which also brings some improvements to both language and libraries to facilitate this feat.

The community also grew. Crates.io is now at more than 70000 crates in stock, and more than 11 billion downloads! The rust subreddit grew from about 122k to more than 162k users, narrowly trailing r/golang. Rust entered the top 20 of the Redmonk index for the first time, and won the Stack Overflow survey’s “Most loved programming language” crown for the sixth year in a row. I’ve had more people ask me for mentoring than ever before.

We have a foundation which is gaining members. The foundation has actually started to do useful stuff, like professionally organizing the operations of crates.io which has so far been done by volunteers. Recently, the DevX initiative has started sponsoring work on Rust. This is great news for Rust and Open Source alike!

That’s not to say all has been roses. The mod team quit due to a problem with the rules not allowing us to enforce the CoC. Fortunately, there is active work underway to fix this problem, and the new mod team also seems to be doing a good job as far as I can tell.

We still have a security flaw in one of the most popular time/date libraries, which most seem to simply have forgotten about. Ok, it’s fixed in time 0.3, but not in chrono so far. At least we have a CVE to remind us of that.

Looking forward, we’re going to see more of the same. The compiler will be getting more powerful while speeding up even more. Features that people have been missing are in the process of being implemented and will arrive in the new year. The error message code will at one point become sentient and decide to send a robot back in time to save mankind from skynet or something. The community will continue to grow, and more Rust jobs will be available, ready to be taken by more Rust programmers.

My guess is that we will see more active involvement from the foundation in the new year, which is great news to the community. The work started after the mod team change will likely conclude within the second quarter of 2022, improving the governance structure and paving the way for even more success in the future.

With a bit of luck we will find a way to harden our systems against supply-chain attacks before they become a real problem. We likely need more integration, documentation and raising awareness.

I still see some risk that there might be a tipping point where the backlash against the out of control grift around blockchains will also harm Rust by association, because many projects in that space use the language because of performance, safety and productivity. Knocking on wood here.

Around us, the pandemic is still raging. Meetup activity has gone online or is reduced. More people work remotely than ever before. My hope and wish is for all of you to stay safe & healthy.
