rustHow to iterate through hashmap values in Rust

Iterating through the values of a HashMap in Rust can be done using the values() method. This returns an iterator over the values of the HashMap. The following example code block shows how to iterate through the values of a HashMap:

use std::collections::HashMap;

let mut map = HashMap::new();
map.insert("a", 1);
map.insert("b", 2);
map.insert("c", 3);

for value in map.values() {
    println!("{}", value);
}

Output example

1
2
3

Code explanation

1. use std::collections::HashMap: This imports the HashMap type from the std::collections module.
2. let mut map = HashMap::new(): This creates a new empty HashMap and stores it in the map variable.
3. map.insert("a", 1): This inserts a key-value pair into the map HashMap.
4. for value in map.values(): This starts an iterator over the values of the map HashMap.
5. println!("{}", value): This prints the current value of the iterator.
