How to Convert an Array of Strings to an Array of Integers in Rust - Step by Step Examples

How to Convert an Array of Strings to an Array of Integers in Rust ?

Answer

To convert an array of strings to an array of integers in Rust, you can use the `parse` method from the `FromStr` trait to parse each string element into an integer.

✐ Examples

1 Convert Strings to Integers

In this example,

We have an array of strings named str_array containing string representations of integers.
We use the parse method from the FromStr trait to transform each element of str_array to an integer.
The resulting array int_array contains the converted integers.
We print the contents of int_array to demonstrate the conversion.

Rust Program

fn main() {
    let str_array = ["10", "20", "30"];
    let int_array: Vec<i32> = str_array.iter().map(|&s| s.parse().unwrap()).collect();
    println!("Converted array of integers: {:?}", int_array);
}

Output

Converted array of integers: [10, 20, 30]
