Confused

Do you ever find yourself using a function that intimidates you? Are there functions that are so terrifying, a mere comment does not sufficiently warn unwitting callers of such function?

With the confusion!() and confused!() macros, you can easily mark a scary function as such:

fn main() -> Result<(), ()> {
	if scary_function(666)?????????? {
		println!("oh shit, oh fuck");
	}

	Ok(())
}

fn scary_function(evil_number: u16) -> confusion!(10, bool) {
	confused!(10, evil_number == 666)
}

Syntax

confusion!(n, ok, err = ())

n is the depth of the Result<...> chain

ok is the type of the final Ok value

err is an optional Err type, if you actually want to use this for error handling

confused!(n, expr)

n is the depth of the Ok(...) chain expr is the final result
