How to Sort Items of a Set in Rust - Step by Step Examples

How to Sort Items of a Set in Rust ?

Answer

To sort the items of a set in Rust, you can convert the set to a vector and then sort the vector using the sort() method.

✐ Examples

1 Sort Items of an Integer Set

In this example,

We create a set named numbers containing some integer elements using the hashset! macro.
We convert the set to a vector using the into_iter() method.
We sort the vector using the sort() method.
Finally, we iterate through the sorted vector and print each element to the console.

Rust Program

use std::collections::HashSet;

fn main() {
    let numbers = hashset![5, 3, 1, 4, 2];
    let mut sorted_numbers: Vec<_> = numbers.into_iter().collect();
    sorted_numbers.sort();
    println!("Sorted numbers:");
    for number in sorted_numbers {
        println!("{}", number);
    }
}

Output

Sorted numbers:
1
2
3
4
5

2 Sort Items of a String Set

In this example,

We create a set named fruits containing some string elements using the hashset! macro.
We convert the set to a vector using the into_iter() method.
We sort the vector using the sort() method.
Finally, we iterate through the sorted vector and print each element to the console.

Rust Program

use std::collections::HashSet;

fn main() {
    let fruits = hashset!['Banana', 'Apple', 'Cherry', 'Date'];
    let mut sorted_fruits: Vec<_> = fruits.into_iter().collect();
    sorted_fruits.sort();
    println!("Sorted fruits:");
    for fruit in sorted_fruits {
        println!("{}", fruit);
    }
}

Output

Sorted fruits:
Apple
Banana
Cherry
Date
