What is a stable way to iterate on a range with custom step?

Question

How should I go if I want to iterate with a custom step in stable Rust? Essentially something like the C/C++

for (in         


        

Answer 1

There is way using let "redefinition":

for i in 0..((n + 1) / 2) {
    let i = i * 2;
    // …
}

Or use Iterator::map:

for i in (0..((n + 1) / 2)).map(|i| i * 2) {
    // …
}
