why is rust treated like a feature by some people?

before i start, i want to say i have nothing against rust or using it, in fact, it's one of my favorite languages of all time. i just don't get why some people treat a program being written in rust as a feature of the program? i understand if it's something where memory issues really could cause big problems like an operating system or a firewall or something like that, but i've seen people use rust as a reason to use something like bat over cat, leftwm, etc., and i just don't get it. could someone shed some light on why people treat rust like that? is it just fanaticism, or is there another reason? again, this post isn't out of any hatred for rust, i'm just confused.
