First we need to add a crate named rand to our project:
In cargo.toml file:
[dependencies]
rand = "0.8"Back to main.rs file:
use rand::Rng;
fn main() {
let mut rng = rand::thread_rng();
let a = rng.gen_range(0..=100);
println!("{}", a)
} We call thread_rng funcion from rand to create a random number generator.
We call gen_range method on this generator ,and pass a range into this method , we pass 0..=100 , means it will generate a integer number between 0 and 100 (include 0 and 100 ) (If we not add = before 100 , then it will not include 100).
