I just found https://google.github.io/comprehensive-rust/ today. Structured course developed by Google for its Android devs.

I found it completely by accident. Was looking at their GitHub repos for something, and saw this in there. I might even try to go through some of it (though I also want to get better at Nim).

I think that’s been asked before. That’d be a massive undertaking, and they also support architectures that I don’t think Rust does (yet).
