rustWhat is the default value of a Rust string?


The default value of a Rust string is an empty string. This is represented by two double quotes with nothing in between, like this: "".

let my_string = "";
println!("{}", my_string);

Output example

The empty string is a valid string, and can be used in the same way as any other string.

Code explanation

  1. let my_string = ""; - This line declares a variable called my_string and assigns it the value of an empty string.
  2. println!("{}", my_string); - This line prints the value of my_string to the console.
