rustHow to format string literal in Rust

String literals in Rust can be formatted using the format! macro. This macro allows you to insert variables into a string literal and format them according to the specified format.

Code example:

let name = "John";
let age = 30;
println!("{} is {} years old", name, age);

Output

John is 30 years old

Explanation:

• let name = "John";: This line declares a variable name and assigns it the value "John".
• let age = 30;: This line declares a variable age and assigns it the value 30.
• println!("{} is {} years old", name, age);: This line uses the format! macro to print out a string literal with the variables name and age inserted into it. The {} symbols indicate where the variables should be inserted.
