rustHow format string with fixed width in Rust

Formatting strings with fixed width in Rust can be done using the format! macro. This macro allows you to specify the width of the string, as well as other formatting options.

Code example:

let name = "John";
let formatted_name = format!("{:10}", name);
println!("{}", formatted_name);

Output

John

Explanation of code parts:

1. let name = "John": This line declares a variable called name and assigns it the value of "John".
2. let formatted_name = format!("{:10}", name): This line uses the format! macro to format the name variable with a width of 10 characters.
3. println!("{}", formatted_name): This line prints the formatted string to the console.
