awesome work as usual!

to summarize my points:

• let's use rust algebraic data types, to define the three levels of our nodes.
• let's follow the rest of the packages and transform our /_data folder into one JSON file, I built a quick PoC in Poc of generating _data.rs from ../_data folder #47.
  • we can later modify the build script, so it generates actual structs that we store directly in the stack instead of the heap for ultimate performance, but that is for later, let's not optimize prematurely.
• let's do it how rustaceans do it, by being as idiomatic as possible.

My bad 😅 my java extension is working behind the scenes (I'll revert those java changes)
