rustHow to find an element in a slice in Rust?

Finding an element in a slice in Rust can be done using the contains() method. This method takes a reference to the element to be found and returns a boolean value indicating whether the element is present in the slice or not.

Example code

let numbers = [1, 2, 3, 4, 5];
let result = numbers.contains(&3);

Output example

true

Code explanation

• let numbers = [1, 2, 3, 4, 5];: This line creates a slice of numbers.
• let result = numbers.contains(&3);: This line calls the contains() method on the numbers slice, passing a reference to the element to be found (in this case, 3).
• true: This is the output of the example code, indicating that the element 3 is present in the numbers slice.
