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.
