rustHow to get all values from a Rust HashMap?

You can get all values from a Rust HashMap using the values() method. This method returns an iterator over the values of the HashMap.

Example code

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

• use std::collections::HashMap: imports the HashMap type from the standard library.
• let mut map = HashMap::new(): creates a new empty HashMap.
• map.insert("a", 1): inserts a key-value pair into the HashMap.
• for value in map.values(): iterates over the values of the HashMap.
• println!("{}", value): prints the value to the console.
