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

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

Answer

To convert a set of floats to a set of strings in Rust, you can use the iter() method to create an iterator over the float set, and then use the map() method to transform each float value into its string representation.

✐ Examples

1 Convert a Set of Floats {1.1, 2.2, 3.3} to Strings

In this example,

First, we create a set of floats named float_set1 with values {1.1, 2.2, 3.3}.
Next, we create an iterator over float_set1 using the iter() method.
We use the map() method on the iterator to transform each float value into its string representation. We pass a closure to the map() method that converts each float value to a string using the to_string() method.
Finally, we collect the mapped values into a new set of strings called string_set1 using the collect() method.

Rust Program

fn main() {
    let float_set1: std::collections::HashSet<f32> = [1.1, 2.2, 3.3].iter().cloned().collect();
    let string_set1: std::collections::HashSet<String> = float_set1.iter().map(|&x| x.to_string()).collect();

    for s in &string_set1 {
        println!("{}", s);
    }
}

Output

1.1
2.2
3.3

2 Convert a Set of Floats {4.5, 5.6, 6.7} to Strings

In this example,

First, we create a set of floats named float_set2 with values {4.5, 5.6, 6.7}.
Next, we create an iterator over float_set2 using the iter() method.
We use the map() method on the iterator to transform each float value into its string representation. We pass a closure to the map() method that converts each float value to a string using the to_string() method.
Finally, we collect the mapped values into a new set of strings called string_set2 using the collect() method.

Rust Program

fn main() {
    let float_set2: std::collections::HashSet<f32> = [4.5, 5.6, 6.7].iter().cloned().collect();
    let string_set2: std::collections::HashSet<String> = float_set2.iter().map(|&x| x.to_string()).collect();

    for s in &string_set2 {
        println!("{}", s);
    }
}

Output

4.5
5.6
6.7
