Rust Program to Iterate over ArrayList using Lambda Expression

Iterate over ArrayList using Lambda Expression

Rust Programming Language

Problem

Rust program that iterates over an ArrayList using a lambda expression.

Input

fn main() {

    // Create a vector of integers

    let vec = vec![1, 2, 3, 4, 5];

    // Use a closure to iterate over the vector and print out each element

    vec.iter().for_each(|&x| println!("{}", x));

}{codeBox}

Output

1

2

3

4

5{codeBox}

Explanation

In this example, the vec variable is a vector of integers that we want to iterate over. We use the iter method to get an iterator over the elements of the vector, and then we use the for_each method to apply a closure to each element of the iterator. The closure takes a reference to each element of the iterator (which we've named x), dereferences it to get the actual value, and then prints it out to the console using println!.

The result of iterating over the elements of the vector and printing out each element using the closure.
