The purpose of the article was to show how to get up and running with rust on a Raspberry Pi, not to show how that rust is easier to use than C for programming a Raspberry Pi.

Plenty of things I do are are word for word the same in C and python. (import math vs. #include <math.h> , math.sin(x) vs. sin(x), etc.)

It is when you want to build something more complex than a blinking light that the differences between languages come out.
