How to merge two vectors without duplicate items in Rust

Answer 1

use std::collections::HashSet;

fn main() {
    let array1 = vec!["rust", "performance", "safety", "concurrency", "rust"];
    let array2 = vec!["performance", "rust", "safety", "rust"];

    let mut set: HashSet<_> = HashSet::new();
    set.extend(array1);
    set.extend(array2);

    let merged_vec: Vec<_> = set.into_iter().collect();

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