I've tried to learn Rust a few times and tbh the tooling just isn't that great. Maybe when Microsoft embraces it in VS (not VS Code!) I'll try again. JetBrains' Rust Rover looks somewhat compelling, but I couldn't get it to work for some reason. Also, I write a lot of code for ancient embedded systems that Rust doesn't support, so it's out for that reason anyway.
I don't remember exactly how, but you can specify a compiler using arcane magic I don't fully understand to compile for a baremetal target. Some people do full OS dev in just Rust, though usually C and ASM are involved to bootstrap. It can be somewhat arcane, though.
There's a blog about writing a micro kernel in Rust that details how to compile for bare metal. It's actually possible to entirely avoid C, although a bit annoying to be sure.
