How to format strings with indentation based on an integer?

Question

Is there a better way to print/format string indentation besides doing:

let text_to_indent = "Indented text!";
for i in 0..indent {
    print!(" ");
}
println!("{}", text_to_indent);

Does Rust have a more convenient way to do this?

Answer 1

println!("{:indent$}Indented text!", "", indent=indent);

(Playground)

The first placeholder does the indentation. It will print the argument 0 (empty string, "") with a padding (with spaces) as specified in argument ident.

Printing a variable can be done like this:

println!("{:indent$}{}", "", text_to_indent, indent=level);
