rustHow to format string in Rust

String formatting in Rust is done using the format! macro. This macro allows you to create a formatted string with placeholders for values that will be filled in later.

Code example:

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

println!("{} is {} years old", name, age);

Output

John is 30 years old

Explanation of code parts:

1. let name = "John"; - This line declares a variable called name and assigns it the value of "John".
2. let age = 30; - This line declares a variable called age and assigns it the value of 30.
3. println!("{} is {} years old", name, age); - This line uses the format! macro to print out a formatted string with the values of name and age in the appropriate places.
