How to borrow in loop in Rust

// plain

Looping in Rust is done using the loop keyword. This keyword allows you to create an infinite loop, which can be used to iterate over a collection of items.

let mut count = 0;

loop {
    count += 1;
    println!("{}", count);
    if count == 10 {
        break;
    }
}

10

The code above creates an infinite loop that prints out the numbers from 1 to 10. The loop keyword is followed by a set of curly braces {} which contain the code that will be executed in the loop. The break keyword is used to exit the loop when the condition is met.

Code explanation

• let mut count = 0;: This line declares a mutable variable count and initializes it to 0.
• loop {: This line starts the loop.
• count += 1;: This line increments the value of count by 1.
• println!("{}", count);: This line prints the value of count to the console.
• if count == 10 {: This line checks if the value of count is equal to 10.
• break;: This line exits the loop.
