Gokrazy for Rust

Hi,
I was wondering: is anyone aware of something like gokrazy but written in Rust?
I have a diy project where I want to use a Raspberry Pi with basically nothing but the kernel and a Rust executable (and probably libc because it'll be needed?). Gokrazy allows you to do essentially that, but in Go. And I want to use rust.
Regards,
Maarten
