so i'm currently digging into rust for kernel development and, as someone with little rust experience to begin with, feel kind of overwhelmed by the entire build process. my two main problems are:

• interoperability with assembly files that make use of the C preprocessor
• configuration beyond simple booleans, i.e. i need user supplied strings/integers in both rust and assembly files

are there any homosexuals in the fediverse who could help me out with this?
