Find Where Two Vecs Diverge In Rust

This isn't a full diff, it gets the place where things diverge and follows the second vec from that point

Code

use std::collections::VecDeque;
use std::cmp::min;

fn main() {
  let primary = vec!["alfa".to_string(), "bravo".to_string()];
  let diff1 = vec![];
  let diff2 = vec!["alfa".to_string()];
  let diff3 = vec!["alfa".to_string(), "bravo".to_string()];
  let diff4 = vec!["alfa".to_string(), "bravo".to_string(), "charlie".to_string()];
  let diff5 = vec!["alfa".to_string(), "echo".to_string(), "charlie".to_string()];
  let diff6 = vec!["echo".to_string()];
  let diff7 = vec!["echo".to_string(), "alfa".to_string()];

  assert_eq!(walk_vecs(&primary, &diff1), vec!["alfa".to_string(), "bravo".to_string()]);
  assert_eq!(walk_vecs(&primary, &diff2), vec!["bravo".to_string()]);
  assert_eq!(walk_vecs(&primary, &diff3), Vec::<String>::from([]));
  assert_eq!(walk_vecs(&primary, &diff4), vec!["charlie".to_string()]);
  assert_eq!(walk_vecs(&primary, &diff5), vec!["echo".to_string(), "charlie".to_string()]);
  assert_eq!(walk_vecs(&primary, &diff6), vec!["echo".to_string()]);
  assert_eq!(walk_vecs(&primary, &diff7), vec!["echo".to_string(), "alfa".to_string()]);

  println!("testing complete");
}

fn walk_vecs(v1: &Vec<String>, v2: &Vec<String>) -> Vec<String> {
  let mut d1: VecDeque<String> = VecDeque::from(v1.clone());
  let mut d2: VecDeque<String> = VecDeque::from(v2.clone());
  let min_length = min(d1.len(), d2.len());
  for _ in 0..min_length {
    if d1[0] == d2[0] {
      d1.pop_front();
      d2.pop_front();
    }
  }
  if d2.len() == 0 && d1.len() != 0 {
    d1.into()
  } else {
    d2.into()
  }
}

Results
