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.
