rustHow do I add padding to a variable in Rust?

Adding padding to a variable in Rust is done using the format! macro. This macro allows you to specify the width of the output and the character to use for padding. For example, the following code will pad a variable with spaces to a width of 10 characters:

let x = 5;
let padded = format!("{:10}", x);
println!("{}", padded);

Output example

     5
