How to check if a Specific Item is present in the Vector in Rust ?

Answer

To check if a specific item is present in a vector in Rust, you can use the contains() method.

✐ Examples

1 Check if Numeric Item is Present in Vector

In this example,

We have a vector named vec containing numeric elements.
We call the contains() method on vec to check if the specified item is present.
We print the result to standard output.

Rust Program

fn main() {
    let vec = vec![1, 2, 3, 4, 5];
    let item = 3;
    let result = vec.contains(&item);
    println!("{:?}", result);
}

Output

true

2 Check if String Item is Present in Vector

In this example,

We have a vector named vec containing string elements.
We call the contains() method on vec to check if the specified item is present.
We print the result to standard output.

Rust Program

fn main() {
    let vec = vec!["apple", "banana", "cherry", "date"];
    let item = "banana";
    let result = vec.contains(&item);
    println!("{:?}", result);
}

Output

true
