How to hash in RUST?

cargo new hash_example
cd hash_example

[dependencies]
sha3 = "0.10"

use sha3::Sha3_256;
use digest::Digest;

pub fn compute_sha3(input: &str) -> String {
    let mut hasher = Sha3_256::new();
    hasher.update(input.as_bytes());
    let result = hasher.finalize();
    format!("{:x}", result)
}

mod sha3_hash;

fn main() {
    let input = "hello world";

    let sha3_result = sha3_hash::compute_sha3(input);
    println!("SHA3-256 hash of '{}': {}", input, sha3_result);
