rustHow do you map strings in Rust?

Strings in Rust are mapped using the HashMap type, which is a part of the standard library. HashMap is a key-value store that allows you to store data using a key and retrieve it using the same key.

Example code

use std::collections::HashMap;

let mut map = HashMap::new();

map.insert("key1", "value1");
map.insert("key2", "value2");

println!("{:?}", map);

Output example

{"key1": "value1", "key2": "value2"}

Code explanation

• use std::collections::HashMap;: imports the HashMap type from the standard library.
• let mut map = HashMap::new();: creates a new HashMap instance.
• map.insert("key1", "value1");: inserts a key-value pair into the HashMap.
• println!("{:?}", map);: prints the contents of the HashMap.
