Rust while Loop

In Rust, you can create a while loop using the while keyword followed by a condition that evaluates to a boolean value. Here's an example:

let mut count = 0;

while count < 10 {
    println!("Count is {}", count);
    count += 1;
}

In this example, the loop will continue to execute as long as the count variable is less than 10. Inside the loop, we're printing the current value of count and then incrementing it by 1 with the count += 1 statement.

It's important to note that the condition in a while loop must eventually become false, otherwise the loop will continue to execute indefinitely. It's also a good idea to use a mutable variable (like count in the example) if you plan on modifying its value inside the loop.
