Stringif! w rdzy

// You can use it in a macro
macro_rules! foo {
	($a:ident) => {
    	println!("{}", stringify!($a))
    }
}

fn main() {
	foo!(hello); // prints `hello`
    
    // Also you can use it to convert an expression to a &str:
    let one_plus_one = stringify!(1 + 1);
	assert_eq!(one_plus_one, "1 + 1");
