9 Companies That Use Rust in Production

9 Companies That Use Rust in Production

Who uses Rust, and what are the benefits of choosing this programming language for your stack?

If you haven’t yet heard, Rust is one of the most promising and most loved programming languages out there.

First created at Mozilla, it has since been adopted by companies like Dropbox, Microsoft, Facebook, and others. Rust’s main benefit is that it enables C-like performance while still keeping the memory safety that we are used to when developing with languages like JavaScript and Python.

In this article, I will look at nine large companies that use Rust and delve into the reasons for their choice.

9 Rust success stories

Dropbox uses Rust for parts of its file synchronization engine. Since the engine is highly concurrent, writing, testing, and debugging it is hard. Therefore, the team chose to rewrite it in Rust. Rust’s static types and heavy compile-time checks give it an advantage over dynamically typed languages like Python when you need to tackle complex codebases and concurrent code.

Rust has been a force multiplier for our team, and betting on Rust was one of the best decisions we made. More than performance, its ergonomics and focus on correctness has helped us tame sync’s complexity. We can encode complex invariants about our system in the type system and have the compiler check them for us. (Source)

"Rust Isn’t Afraid to be Imperfect as Long as we Ship something Useful"

Steve Klabnik is a member of the Rust core team, an active open-source contributor, and author of The Rust Programming Language, Rails 4 in Action, and Designing Hypermedia APIs books. In 2012 and 2016, we invited Steve to speak at the RailsClub (now RubyRussia) conference. Since then, Steve has been working on Rust a lot, did a lot of interesting things and we realized that we should definitely interview him once again!

Prevent Breaking Code Changes in Future Releases using `non exhaustive` enums in Rust

Hello everyone, recently I have come across a feature in Rust, known as non_exhaustive. It was introduced in Rust 1.40.0 . This attribute prevents source code-breaking changes in projects downstream.
