rustHow to add a value to a Rust HashMap?

Adding a value to a Rust HashMap is done using the insert method.

use std::collections::HashMap;

let mut map = HashMap::new();

map.insert("key", "value");

The code above creates a new HashMap and inserts a key-value pair into it. The insert method takes two arguments, the key and the value.

1. use std::collections::HashMap: imports the HashMap type from the std::collections module.
2. let mut map = HashMap::new(): creates a new HashMap and assigns it to the map variable.
3. map.insert("key", "value"): inserts a key-value pair into the map HashMap.

For more information, see the Rust documentation.
