How to check if Two Sets are Equal in Rust ?

Answer

In Rust, you can check if two sets are equal by comparing them using the '==' operator.

✐ Examples

1 Check Equality of Two Sets

In this example,

We define two sets, set1 and set2, containing elements of the sets.
We use the '==' operator to compare the sets for equality.
If the two sets contain the same elements, the '==' operator returns 'true'; otherwise, it returns 'false'.

Rust Program

fn main() {
    let set1: std::collections::HashSet<_> = [1, 2, 3, 4].iter().cloned().collect();
    let set2: std::collections::HashSet<_> = [1, 2, 3, 4].iter().cloned().collect();
    
    let are_equal = set1 == set2;
    
    println!("{:?}", are_equal);
}

Output

true

2 Check Equality of Unequal Sets

In this example,

We define two sets, set1 and set2, containing elements of the sets.
We use the '==' operator to compare the sets for equality.
If the two sets contain different elements or have a different number of elements, the '==' operator returns 'false'.

Rust Program

fn main() {
    let set1: std::collections::HashSet<_> = [1, 2, 3, 4].iter().cloned().collect();
    let set2: std::collections::HashSet<_> = [4, 3, 2, 1].iter().cloned().collect();
    
    let are_equal = set1 == set2;
    
    println!("{:?}", are_equal);
}

Output

false
