In particular, the elixir_ale library is a very pleasant interface to various bits of hardware you might want to interact with at the GPIO/i2c/etc level.
It'd be interesting to explore something similar to the bitstring[1] library for Ocaml. Where should one start if exploring syntax extensions for Rust. I haven't looked into rust in a while now so i'm not sure how far one can get with macros these days.
