I work at Materialize, which is writing a database in Rust. We use some `unsafe` code, but it's a very small proportion of the overall codebase and quite well abstracted away from the rest of the non-unsafe code. To be fair, we're trying to do a bit of a different thing (in-memory incrementally maintained views on streaming data) than most existing databases, so you could argue that it is not an apples-to-apples comparison. But there are plenty of other databases written in non-C++ languages -- there is even TiDB which is written in Rust too.
