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.
