rustHow do I check if a variable is in a list of values in Rust?


You can check if a variable is in a list of values in Rust by using the contains method. This method takes a reference to the list and the value to search for as parameters.

Example code

let list = [1, 2, 3, 4, 5];
let value = 3;

if list.contains(&value) {
    println!("The list contains the value!");
}

Output example

The list contains the value!

Code explanation

  • let list = [1, 2, 3, 4, 5];: This line creates a list of values.
  • let value = 3;: This line creates a variable to search for in the list.
  • if list.contains(&value): This line checks if the list contains the value.
  • println!("The list contains the value!");: This line prints a message if the list contains the value.
