I build all my projects with Rust and Typescript (https://github.com/brainless). I had started learning Rust around 2023 but was progressing very slow. Since I left writing (or even reading) code line by line about a year ago, I build exclusively with Rust and Typescript. API types are generated from Rust. All my projects have a shared-types folder with a utility to generated Typescript types. I have a template that I use for each of my projects: https://github.com/brainless/rustysolid.
I am from a Python background (11 years or so), PHP before that and C/C++ in college days. Rust works very well with coding agents. The amount of code in training data may be less but I would rather have the agent fight the compiler. Given that OpenAI and Anthropic seem interested in Rust, chances are that there is a ton of synthetic code generated with Rust.
