To be honest I think it should be the other way around.

Typescript is a good high-level language that is versatile and well generated by LLMs and there is a good support for various linters and other code support tools. You can probably knock out more TS code then Rust and at faster rate (just my hypothesis). For most intents and purposes this will be fine but in case you want faster, lower-level code, you can use an LLM-backed compiler/translator. A specialised tool that compiles high level code to rust will be awesome actually and I can see how it could potentially be a dedicated agent of sorts.
