If you are interested, I've started to port over Handmade Hero to Rust (using SDL for now). I will have some blog entries walking through the process. Once the platform-specific pieces are finished, I'll stick to writing posts there about gotchas that I run into or major differences with the Rust version and the C version.
Originally I was going to write my own language and use Handmade Hero as a real-world test, but I've found that Rust has most of what I was going to build.
I'm very new to Rust, so it might not be the most idiomatic Rust code. Anyhow, if you're interested, take a look.
