rustHow do I format a variable in Rust?

Formatting a variable in Rust is done using the format! macro. This macro takes a format string and a list of arguments, and returns a String containing the formatted text.

let name = "John";
let age = 30;

let formatted_string = format!("My name is {}, and I am {} years old.", name, age);
println!("{}", formatted_string);

Output example

My name is John, and I am 30 years old.
