rustHow to iterate by increment of 2 in Rust

Iterating by increment of 2 in Rust can be done using the step_by method of the Iterator trait. This method takes a usize argument which is the number of steps to take.

Example code

let mut iter = 0..10;
for i in iter.step_by(2) {
    println!("{}", i);
}

Output example

0
2
4
6
8

Code explanation

• let mut iter = 0..10;: creates an iterator from 0 to 10 (not including 10)
• for i in iter.step_by(2): iterates over the iterator, taking steps of size 2
• println!("{}", i);: prints the current value of the iterator
