> You and other Rust enthusiasts are missing the point. Please, there's no need to make this "us vs them" :) I explained what's happening without saying it's the best approach possible. > In C or any C-based language or even Python, you can just call either a function passing the reference to the GPIO pointer, or just GPIO |= 1. You can do this in Rust just fine by using raw pointers (references). The point is, in complex programs (not the example from the embedded rust book necessarily) it's possible to make memory safety mistakes. While in Rust it is not unless you choose so. This is not about which approach is better, it's a matter of fact. Whether you prefer the one or the other is your personal choice.
