Loop Through A BTreeMap In Rust

use std::collections::BTreeMap;

fn main() {
  let mut items: BTreeMap<String, String> = BTreeMap::new();
  items.insert("alfa".to_string(), "bravo".to_string());
  items.insert("charlie".to_string(), "delta".to_string());

  items.iter().for_each(|(key, value)| {
    println!("Key: {} - Value: {}", key, value);
  });
}
