Rust❤️ 벡터에 Vector내가 원하는 숫자 원하는 크기만큼 랜덤 숫자 담기 ^^;

그냥 맘대로 숫자나오게 균등따위는 없음 예문

use rand::Rng;

fn main() {
    let mut rng = rand::thread_rng();

    let vals: Vec<u64> = (0..1000).map(|_| rng.gen_range(0..500)).collect();

    println!("{vals:?}");
}

균등한 숫자를 담는 방법

 

(0..10)이건 벡터에 10개의 숫자를 담겠다는 코드

 

위에 (0..1000) 숫자 범위는 0~1,000을 의미함.

 

use rand::distributions::Uniform;
use rand::Rng;

fn main() {
    let mut rng = rand::thread_rng();
    let range = Uniform::new(0, 1000);

    let vals: Vec<u64> = (0..10).map(|_| rng.sample(&range)).collect();

    println!("{:?}", vals);
}
