How to Shuffle a Vector in Rust ?

Answer

To shuffle a vector in Rust, you can use the `shuffle` method from the `rand` crate.

✐ Examples

1 Shuffle a Vector of Integers

In this example,

We create a vector named int_vector containing integers.
We import the necessary dependencies including the rand crate.
We use the shuffle method from the rand::seq::SliceRandom trait to shuffle the elements of the vector.

Rust Program

extern crate rand;

use rand::seq::SliceRandom;

fn main() {
    let mut int_vector = vec![1, 2, 3, 4, 5];
    int_vector.shuffle(&mut rand::thread_rng());
    println!("{:?}", int_vector);
}

Output

[2, 5, 4, 1, 3]

2 Shuffle a Vector of Characters

In this example,

We create a vector named char_vector containing characters.
We import the necessary dependencies including the rand crate.
We use the shuffle method from the rand::seq::SliceRandom trait to shuffle the elements of the vector.

Rust Program

extern crate rand;

use rand::seq::SliceRandom;

fn main() {
    let mut char_vector = vec!['a', 'b', 'c', 'd', 'e'];
    char_vector.shuffle(&mut rand::thread_rng());
    println!("{:?}", char_vector);
}

Output

[d, c, e, b, a]
