rustHow to create a HashMap of traits in Rust?

A HashMap is a data structure in Rust that stores key-value pairs. It is a collection of unique keys and their associated values. To create a HashMap of traits, you can use the HashMap::new() method.

use std::collections::HashMap;

let mut traits = HashMap::new();

traits.insert("strength", 10);
traits.insert("intelligence", 8);
traits.insert("charisma", 5);

The output of the example code is:

()

Code explanation

1. use std::collections::HashMap; - This imports the HashMap module from the standard library.

2. let mut traits = HashMap::new(); - This creates a new, empty HashMap called traits.

3. traits.insert("strength", 10); - This inserts a key-value pair into the HashMap, with the key being "strength" and the value being 10.

4. traits.insert("intelligence", 8); - This inserts a key-value pair into the HashMap, with the key being "intelligence" and the value being 8.

5. traits.insert("charisma", 5); - This inserts a key-value pair into the HashMap, with the key being "charisma" and the value being 5.
