Introduction to Loops in Rust

Posted: December 2022

Welcome to our beginner's guide on loops in Rust! In this tutorial, we will be covering the basics of how to create and use loops in Rust.

What are loops?

In programming, a loop is a way to repeatedly execute a block of code until a certain condition is met. Loops are useful for performing repetitive tasks, such as iterating through an array of items or counting from 1 to 10.

Types of Loops in Rust

Rust has several types of loops available, including while, for, and loop.

while Loops

while loops repeatedly execute a block of code as long as a certain condition is true. For example:

let mut count = 0;
while count < 10 {
    println!("Count: {}", count);
    count += 1;
}

This code will print "Count: 0" to "Count: 9" to the console, incrementing the count variable by 1 each time.

for Loops

for loops are used to iterate through a collection of items, such as an array or a range of numbers. For example:

let numbers = [1, 2, 3, 4, 5];
for number in numbers.iter() {
    println!("Number: {}", number);
}

This code will print "Number: 1" to "Number: 5" to the console, iterating through each item in the numbers array.

loop Loops

loop loops execute a block of code indefinitely until a certain condition is met. It is important to include a way to break out of the loop, or it will continue indefinitely. For example:

let mut count = 0;
loop {
    println!("Count: {}", count);
    count += 1;
    if count == 10 {
        break;
    }
}

This code will print "Count: 0" to "Count: 9" to the console, incrementing the count variable by 1 each time, and
