I wish someone would finish a decent database in Rust. At least get it to 1.0 stable and go on from there.
- Limbo: "Limbo is a work-in-progress..."
- Sled [1]. Not sure what's going on there. Last release 3 years ago, but a constant stream of "alpha" versions that never get released.
SQLite with Rust bindings seems to be the go-to system. Depending on C packages is often a headache when cross-compiling, though.
The problem that Rust runs into is that the community settled on wanting enforced semver extremely quickly, combined with an overall tendency to really not want to do post-1.0 releases if they can help it.
The result is that most Rust crates sit on the 0.x version forever (since anything before 1.0 in semver is pretty much a free-for-all), even though they're probably going to be perfectly usable in most cases with the same library breakage you expect in other languages.
IMO it just shows another dent in thinking that a simple string can confer any information about the API contracts on offer. Semver is a neat indicator, but practically that's all it is.
SurrealDB [1] is a fairly complete database written in Rust. I've used it for fairly small web apps and it felt comfortable to work with coming from MongoDB.

I recommend `rusqlite` or `heed` (`lmdb` wrapper, key-value database). I think `sled` is abandoned.
influxdb is great
Starting projects is fun and easy. Finishing is not.
