I have a vector where the element is a (String, String)
. How can I randomly pick one of these elements?
You want the rand
crate, specifically the choose
method.
use rand::seq::IndexedRandom; // 0.9.0
fn main() {
let vs = vec![0, 1, 2, 3, 4];
match vs.choose(&mut rand::rng()) {
Some(i) => println!("{}", i),
None => println!("Nothing!")
}
}
