The Basic Formatting
Explore how to format strings in Rust using placeholders, positional and named arguments, and printing traits. This lesson teaches you to output single or multiple values correctly using println!(), manipulate numerical formats like binary and hexadecimal, and apply debug traits for simplified output. You'll gain practical skills for displaying formatted data efficiently in Rust programs.
In the previous lesson, we saw how we could print a string to the console. But what if we want to print strings in a particular format? Rust can help by using placeholders.
Note: In Rust, we cannot directly print numbers or variables within the
println!()macro, unlike other languages. We need a placeholder{}.
