How to Convert a Vector of Strings to a Vector of Integers in Rust - Step by Step Examples

How to Convert a Vector of Strings to a Vector of Integers in Rust ?

Answer

To convert a vector of strings to a vector of integers in Rust, you can use the `parse()` method along with the `collect()` method.


✐ Examples

1 Convert Vector of Strings to Vector of Integers

In this example,

  1. We create a vector of strings named str_vector.
  2. We use the parse() method to parse each string into an integer.
  3. We use the collect() method to collect the parsed integers into a vector of integers.

Rust Program

let str_vector = vec!["1", "2", "3", "4", "5"];
let int_vector: Vec<i32> = str_vector.iter().map(|s| s.parse().unwrap()).collect();
println!("{:?}", int_vector);

Output

[1, 2, 3, 4, 5]

Summary

In this tutorial, we learned How to Convert a Vector of Strings to a Vector of Integers in Rust language with well detailed examples.
