Im trying to make a function similar to this
pub const fn insert(num1:i32, num2:i32) -> &'static str {
formatcp!("n1:{}, n2:{}" , num1, num2)
}
But num1/num2 are not const. I think this would be possible as a macro but im not experienced in macros.
Does it help?
macro_rules! insert {
($n1:expr, $n2:expr) => {
concat!("n1: ", $n1, " , n2: ", $n2)
};
}
const TEST_1: &str = insert!(1, 2);
const TEST_2: &str = insert!(2, 3);
fn main() {
println!("{}", TEST_1);
println!("{}", TEST_2);
}
