Rustroid, a Rust IDE for Android

I can see why the author did it, and I always respect a person willing to scratch their own itch and maybe help out other people with theirs in the process. With that said, why would anybody who has any other option want to code - let alone build - software on a phone?

Then again, maybe there's plenty of people out there who haven't got any other options. And anything that makes people's phones more like a real computer under their control is a good thing in my book.
