Nothing is implemented

there's probably something i'm not getting here, but i checked out the builder and the bitfield code and they are empty. what's happening?

The proc-macro-workshop is meant to guide you through Rust proc. macros by implementing those crates yourself with guidance by the accompanied comments, docs, initial code structure etc.

Learning by doing.

I did it long time ago and can heavily recommend doing it yourself if your goal is to become proficient with Rust proc. macros.
