Working as a Rust dev (linux.community)

What essential skills/knowledge would you say are/is required to work as a Rust dev?

I did couple of small/mediumish personal projects in Rust using axum with sea-orm and later tauri with leptos. That's on top of many years of experience working as a Java/Javascript dev and occasionally touching things like Python or Flutter. Most of things like databases and web stuff is transferable but what strictly Rust concepts are required to work as a Rust dev? In what fields it's used the most?

Hey, you're on a similar path to me. I've been on a Rust job for the past year.

Being a general-purpose programming language Rust can be used in a lot of contexts. The work I'm doing is all API server stuff, which I'm sure you already have a solid background in. There are some niches where Rust stands out that might be worth studying depending on your interest, but none of these are essential to Rust work generally.

Crypto startups seem to be enthusiastic adopters of Rust. It's not an area I want to get into personally, but this is likely the fastest path to a Rust job.
Rust is probably the best language for compiling to WASM for running in browsers, in lightweight server-less functions, and as plugins. That could dovetail with your frontend experience. Although it's a bit of an uphill battle to argue for WASM over Javascript in these cases.
Rust makes an appealing choice for embedded programming as a safer alternative to C. This kind of work involves learning to program with nostd, and learning about controlling hardware.
In non-embedded systems low-level pieces like device drivers are another good candidate for Rust.
