rustHow to map values in a Rust HashMap?

Mapping values in a Rust HashMap is done using the insert method. This method takes two arguments, a key and a value, and adds them to the HashMap.

Example

let mut map = HashMap::new();
map.insert("key1", "value1");
map.insert("key2", "value2");

Output example

()

Code explanation

• let mut map = HashMap::new();: creates a new, empty HashMap
• map.insert("key1", "value1");: inserts a key-value pair into the HashMap
• map.insert("key2", "value2");: inserts another key-value pair into the HashMap
