How to Iterate Over a Vector in Rust - Step by Step Examples

How to Iterate Over a Vector in Rust ?

To iterate over a vector in Rust, you can use a for loop to access each element of the vector one by one.

In this example,

First, we create a vector named vec with a series of integer values using the vec! macro.
We then use a for loop to iterate over each element of the vector. The loop variable item will take on the value of each element in the vector, one at a time.
Inside the loop, we use the println! macro to print the current value of the loop variable item.
The println! macro sends the value of item to the console, allowing us to see each element of the vector as it is processed.

fn main() {
    let vec = vec![10, 20, 30, 40, 50];
    for item in &vec {
        println!("{}", item);
    }
}

In this example,

First, we create a vector named vec with a series of string values using the vec! macro.
We then use a for loop to iterate over each element of the vector. The loop variable item will take on the value of each element in the vector, one at a time.
Inside the loop, we use the println! macro to print the current value of the loop variable item.
The println! macro sends the value of item to the console, allowing us to see each element of the vector as it is processed.

fn main() {
    let vec = vec!["apple", "banana", "cherry", "date", "elderberry"];
    for item in &vec {
        println!("{}", item);
    }
}

apple
banana
cherry
date
elderberry
