How to Write Data Valudators in Python for Pidantic?

Rastisna is not quite as pretty as it could be. And i really don't want to build, basically, another way of sharing dependencies beyond pipi. The bench marks indicate four to 50 times faster. There are a few more optimizations i can make. It'll get a tiny bit slower when it's wrapped in pidantic,. But a tiny amount sot. I think those are realistic numbers.
