Rust by Example

while

The while keyword can be used to run a loop while a condition is true.

Let's write the infamous FizzBuzz using a while loop.

fn main() {

// A counter variable

let mut n = 1;

// Loop while `n` is less than 101

while n < 101 {

if n % 15 == 0 {

println!("fizzbuzz");

} else if n % 3 == 0 {

println!("fizz");

} else if n % 5 == 0 {

println!("buzz");

} else {

println!("{}", n);

}

// Increment counter

n += 1;

}

}
