Bit of a red flag if you really can't.

It's basically TypeScript but runtime exceptions are impossible. If it compiles, it works - so the _only_ thing you worry about is how you organised your code (abstractions, domains, etc) and if the logic is correct.
It saves a lot of time in PR reviews because you only really complain about logic or code organization.
By contrast, C#, Go, Java all have runtime exceptions for things like null pointers and race conditions. That means, when reviewing code, you have to be on the lookout for those things in addition to the logic and structure.
On the single threaded side, TypeScript is great, but JavaScript runtime performance and resource utilization is obscene. With Rust basically being TypeScript but without those limitations (and also natively supporting more frontend frameworks without transpilers), what is the use case for TypeScript (other than legacy software already being written in JavaScript or TypeScript)?
You can write Rust with your eyes closed and it'll probably work.
I also have years of experience with Rust, but I moved off Rust a few years back simply because I'm sick of the anemic stdlib and lack of mature ecosystem around anything even one inch off the beaten path. Cargo is a shitshow and Rust forces you into an npm-like experience for a whole bunch of functionality that ought to be included in the box. You're juggling libraries with versions like 0.1.2 of which there's seven, none of which are feature complete and five of which are semi abandoned. Then you run into the orphan rule trying to fix or extend any of them.
I kind of think some other language will come along, take the borrow checker, take all the type conveniences that Rust stole from OCaml that make Rust so nice, glue it all to a Python/Go/dotnet style fat stdlib, complete with an optional GC for all the things that don't actually need bare metal performance (just stick an arena in stdlib), and Rust will feel like a clunker by comparison.
That'd be a dream to me.
