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 calledname
and assigns it the value"John"
. -
let message = format!("Hello, {}!", name);
- This uses theformat!
macro to insert the value of thename
variable into the string"Hello, {}!"
. -
println!("{}", message);
- This prints the value of themessage
variable to the console.
