How to get the difference between two arrays in Rust

Answer 1

fn main() {
    let array1 = [1, 2, 3, 4, 5];
    let array2 = [4, 5, 6, 7, 8];

    let difference: Vec<_> = array1.iter()
                                   .filter(|&item| !array2.contains(item))
                                   .collect();

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

 
    
/*

[1, 2, 3]
   
*/
