rustRust null string example

A Rust null string is a string that has a length of zero. It is represented by a double quotation mark with nothing in between.

Example code

let s = "";
println!("{}", s.len());

Output example

0

The code above creates a string s with nothing in between the double quotation marks. The len() method is then used to print the length of the string, which is 0.
