rustHow to clone a Rust HashMap?

Cloning a Rust HashMap is a simple process. It can be done using the clone() method.

let mut map1 = HashMap::new();
map1.insert("a", 1);
map1.insert("b", 2);

let map2 = map1.clone();

This will create a new HashMap called map2 which is a clone of map1.

Code explanation

1. let mut map1 = HashMap::new(); - creates a new HashMap called map1
2. map1.insert("a", 1); - inserts a key-value pair into map1
3. map1.insert("b", 2); - inserts another key-value pair into map1
4. let map2 = map1.clone(); - creates a clone of map1 called map2
