Since this question was asked, the itertools crate, has become fairly standard as a dependency. You can do what you want very simply with the step() method:

extern crate itertools; // 0.7.8
use itertools::Itertools;

fn main() {
    for i in (0..=10).step(2) {
        println!("i = {}", i);
    }
}

In your Cargo.toml:

[dependencies]
itertools = "0.7.8"
