rustHow do I check if a string is empty in Rust?
You can check if a string is empty in Rust by using the is_empty()
method. This method returns a boolean value indicating whether the string is empty or not.
Example code
let my_string = String::new();
if my_string.is_empty() {
println!("String is empty");
}
Output example
String is empty
Code explanation
let my_string = String::new();
: This line creates a new empty string.if my_string.is_empty()
: This line checks if the string is empty.println!("String is empty");
: This line prints a message if the string is empty.
