In this program, we will create a HashSet to store integer items and then we will insert items using the insert () method and iterate HashSet items using the "for" loop.
The source code to iterate HashSet items using the "for" loop is given below. The given program is compiled and executed successfully.
// Rust program to iterate HashSet items
// using "for" loop
use std::collections::HashSet;
fn main() {
let mut set:HashSet<i32> = HashSet::new();
set.insert(10);
set.insert(20);
set.insert(30);
set.insert(40);
set.insert(50);
println!("HashSet: ");
for item in set
{
print!("{} ",item);
}
}
Output:
HashSet:
40 50 10 20 30
Explanation:
Here, we created a HashSet to store integer elements. Then we added items using the insert() method. After that, we iterated HashSet items using the "for" loop and printed them.
