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

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

Answer

To convert a set of strings to a set of floats in Rust, you can use the parse() method along with the collect() method to transform each string value into its corresponding float value.


✐ Examples

1 Convert a Set of Strings ["1.1", "2.2", "3.3"] to Floats

In this example,

  1. First, we create a vector of strings named string_vec1 with values vec!["1.1", "2.2", "3.3"].
  2. Next, we use the parse() method on each string element of string_vec1 to parse it into a float value.
  3. We use the collect() method to collect the parsed float values into a HashSet named float_set1.

Rust Program

use std::collections::HashSet;

fn main() {
    let string_vec1 = vec!["1.1", "2.2", "3.3"];
    let float_set1: HashSet<f64> = string_vec1
        .iter()
        .map(|s| s.parse::<f64>().unwrap())
        .collect();
    println!("{:?}", float_set1);
}

Output

{"1.1", "2.2", "3.3"}

2 Convert a Set of Strings ["4.5", "5.6", "6.7"] to Floats

In this example,

  1. First, we create a vector of strings named string_vec2 with values vec!["4.5", "5.6", "6.7"].
  2. Next, we use the parse() method on each string element of string_vec2 to parse it into a float value.
  3. We use the collect() method to collect the parsed float values into a HashSet named float_set2.

Rust Program

use std::collections::HashSet;

fn main() {
    let string_vec2 = vec!["4.5", "5.6", "6.7"];
    let float_set2: HashSet<f64> = string_vec2
        .iter()
        .map(|s| s.parse::<f64>().unwrap())
        .collect();
    println!("{:?}", float_set2);
}

Output

{"4.5", "5.6", "6.7"}
