How to check if Specified Element is present in the Array in Rust - Step by Step Examples



How to check if Specified Element is present in the Array in Rust ?

Answer

To check if a specified element is present in an array in Rust, you can use methods like contains or a loop to iterate through the array and compare each element.



✐ Examples

1 Check if Element 30 is present in Integer Array using contains

In this example,

  1. We create a vector named numbers with values 10, 20, 30, 40, 50.
  2. We use the contains method to check if element 30 is present in the vector.
  3. The contains method returns true if the element is found, otherwise false.

Rust Program

fn main() {
    let numbers = vec![10, 20, 30, 40, 50];
    let element = 30;
    let is_present = numbers.contains(&element);
    println!("Element 30 is present: {}", is_present);
}

Output

Element 30 is present: true

2 Check if Element 'banana' is present in String Array using loop

In this example,

  1. We create a vector named fruits with values 'apple', 'banana', 'cherry'.
  2. We use a for loop to iterate through the vector and compare each element with the specified element 'banana'.
  3. If the element is found, we set a boolean variable found to true; otherwise, it remains false.

Rust Program

fn main() {
    let fruits = vec!["apple", "banana", "cherry"];
    let element = "banana";
    let mut found = false;
    for fruit in fruits {
        if fruit == element {
            found = true;
            break;
        }
    }
    println!("Element 'banana' is present: {}", found);
}

Output

Element 'banana' is present: true
