rustHow to iterate hashmap in loop in Rust

Iterating over a HashMap in Rust can be done using a for loop. The syntax for this is as follows:

for (key, value) in &hashmap {
    // do something with key and value
}

The ## Code explanation

• for: the keyword used to start a loop
• (key, value): the variables used to store the key and value of each entry in the HashMap
• &hashmap: the reference to the HashMap being iterated over
• // do something with key and value: the code that will be executed for each entry in the HashMap
