We have built Rust bindings to the TileDB tensor storage engine. As good Rustaceans do, we're open-sourcing the bindings and are quite excited about the possibilities that universal tensor storage open up.
Rust looks like an increasingly important part of the future of scientific programming. It's as fast as C++, as flexible as Python, and does packaging better than even R. It is also very difficult to learn, and demands a lot of cognitive investment. On balance, the ability to write clean, fast, and safe code is worth it, but be prepared to re-learn programming.
