Is it just me, or does this seem a surprisingly bad teaching aid? I mean, it's correct and concise, but it almost distracts from the things that actually matter. I feel if I was learning Rust again this would've been almost useless, if not actually demotivating (because of how much complexity it shoves in your face all at once).
It reminds me of one of the ways of visually laying out elementary particles according to the Standard Model. And now I wonder how much that representation is also actually detrimental to its use as a teaching aid.
