Making this code more idiomatic seems like a really cool opportunity to get some Rust experience. I imagine there's a ton of low-hanging fruit in here, especially given how minimal and modular the different utilities tend to be. And at the same time, you're touring idioms and optimizations copied from some of the most refined C code out there.
