How to Sort an Array in Rust ?

Answer

To sort an array in Rust, you can use the sort() method from the standard library.

✐ Examples

1 Sort Integer Array in Ascending Order

In this example,

We create a mutable integer array numbers with values 5, 2, 8, 1, 6.
We use the sort() method from the standard library to sort the array in ascending order.
The sort() method sorts the array elements in ascending order.
Finally, we print the sorted array numbers to the console.

Rust Program

fn main() {
    let mut numbers = [5, 2, 8, 1, 6];
    numbers.sort();
    println!("Sorted array in ascending order: {:?}", numbers);
}

Output

Sorted array in ascending order: [1, 2, 5, 6, 8]

2 Sort Integer Array in Descending Order

In this example,

We create a mutable integer array numbers with values 5, 2, 8, 1, 6.
We define a custom sorting closure that sorts in descending order.
We use the sort_by() method with our custom closure to sort the array in descending order.
Finally, we print the sorted array numbers to the console.

Rust Program

fn main() {
    let mut numbers = [5, 2, 8, 1, 6];
    numbers.sort_by(|a, b| b.cmp(a));
    println!("Sorted array in descending order: {:?}", numbers);
}

Output

Sorted array in descending order: [8, 6, 5, 2, 1]
