Yeah, based on speed. D is a good language, but it doesn't really provide any new compelling safety and robustness like Rust.

On the bonus side, if you want to get some brief experience writing useful Rust code before you start your project, you can contribute to Redox. It's fairly easy to set up a dev environment, and then you can contribute to the project.

On the D side of things, the Tour on their website is probably going to be good enough for you to learn the language. It also has a more extensive standard library.

For Rust, I recommend the book, second edition.
