Rust

I'm mostly using Rust for a spare time Visual Novel Engine (and Visual Novel) project.

I picked Rust, because I wanted to do something productive with my higher-free-macro crate (which is a tech-demo, but hey, if I have written it, I can just as well use it for something). If you want to get an idea how scripting the VNs in that engine will work, check out the "text adventure" example in higher-free-macro. However, Rust is definitely not an ideal choice for this project. Since performance usually isn't a concern for visual novels, a higher-level, pure functional language like Haskell or Lean4 would probably have been a better option.

Apart from that I'm using it for many smaller things. For instance I've written a small tool for my status bar, swaystatus. (I was not aware that i3status-rust exists when I started working on it, and now I am already committed.) Here I chose Rust mainly because I wanted to learn about Foreign Function Interface in Rust. While I didn't upload the sources to github until recently, I mostly had been working on this tool several years ago, when I still was a Rust newbie. However, I got back to this project some weeks ago, when I realized that I would like to have an ALSA volume display, which is now in a WIP state on a separte branch.

I'm also using Rust for some out-of-tree prototypes at work. In this case the main reason for choosing Rust is development speed. I'm using Iced.rs to build those prototype GUIs, and Iced is an amazing toolkit. Making a prototype with it is shockingly fast. If I were to do something similar with basically any other GUI toolkit, it would take me significantly longer.

And last, but not least: I've published a free app for SailfishOS which is compatible with passwordmaker.org: Passfish, and its underlying library, passwordmaker-rs. Here I chose Rust, because it's way less error prone than C++ (and let's better not talk about QML JavaScript). Also, I wanted to show that using Rust for SailfishOS app development is viable, and that it's actually a quite pleasant experience. (If you want to try passfish, builds are available via the official SailfishOS store, or on OpenRepos).
