rustHow do I add a variable to a string in Rust?
Adding a variable to a string in Rust is done using the format! macro. This macro allows you to insert variables into a string.
Example code
let name = "John";
let message = format!("Hello, {}!", name);
println!("{}", message);Output example
Hello, John!The code above consists of three parts:
-
let name = "John";- This declares a variable callednameand assigns it the value"John". -
let message = format!("Hello, {}!", name);- This uses theformat!macro to insert the value of thenamevariable into the string"Hello, {}!". -
println!("{}", message);- This prints the value of themessagevariable to the console.
