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

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

Answer

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


✐ Examples

1 Convert Vector of Strings to Vector of Floats

In this example,

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

Rust Program

let str_vector = vec!["1.5", "2.5", "3.5", "4.5", "5.5"];
let float_vector: Vec<f64> = str_vector.iter().map(|s| s.parse().unwrap()).collect();
println!("{:?}", float_vector);

Output

[1.5, 2.5, 3.5, 4.5, 5.5]

Summary

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