Data scientist/engineer here. I write Java by day, Rust by night and in both I embrace a data-driven design, where I first carefully lay out the data so that it's easy to use within the code. In hot loops, I avoid dynamic dispatch for its runtime cost. I don't embrace the FP style either because while I generally limit mutation (`final` almost everywhere), I use mutation where it leads to code that is easy to understand, which would be exceedingly "clever" in FP style.
