boa
Boa is an embeddable and experimental Javascript engine written in Rust. Currently, it has support for some of the language.
Is this an experimental only JS engine or do you aim to implement the entire ECMAscript specification?
I have been following the Rust Boa project, but I think that it isn't production ready, yet. https://github.com/boa-dev/boa

GQL
GitQL is a extensible SQL-like query language and SDK to perform queries on various data sources such .git files with supports of most of SQL features such as grouping, ordering and aggregation and window functions and allow customization like user-defined types and functions
-
There was also an option to use Rust and wasmi for the runtime, but although it worked on emulators like PPSSPP, errors occurred on the actual hardware (as shown in the screenshot below).

Project mention: Crafting Interpreters with Rust: On Garbage Collection | news.ycombinator.com | 2024-07-31
This is really well-written!
Shameless plug: you may want to check out https://github.com/ajeetdsouza/loxcraft. I too followed the path of "ignore safe Rust for maximum performance". It got pretty close to the C version, even beating it on some benchmarks.

Project mention: Crafting Interpreters with Rust: On Garbage Collection | news.ycombinator.com | 2024-07-31
Crafting Interpreters is such an amazing work.
There's at least one other Rust implementation of lox that I know of (https://github.com/tdp2110/crafting-interpreters-rs) (no unsafe)
It's always interesting to see how different people approach the problems in their own language or relative isolation. I agree with the author of the article, the real value of the original work lies in avoiding copy and paste.

And what it make this even better, is that you can also write `SQL` so you can have the best of both worlds.
BTW, I think this idea can be move even further and my take is at https://tablam.org
