How to convert map values to a vector in Rust

Answer 1

use std::collections::HashMap;

fn main() {
    let mut hmp = HashMap::new();
    
    hmp.insert("Red", 30);
    hmp.insert("Green", 57);
    hmp.insert("Blue", 86);
    hmp.insert("Yellow", 102);
    
    // Convert values to a Vec<i32>
    let values: Vec<i32> = hmp.values().cloned().collect();

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