What? Returning an int does in fact mean that the method can return -2. I have no idea what your argument is with this, because you seem to be disagreeing with the person while actually agreeing with them.

Though in this case it's more like knowing that the specific way you call the function in foo.rs will never get back a -2. fn bar(n: i32, allow_negative: bool) -> i32 { let new = n * 2; if allow_negative || new >= 0 { new } else { 0 } } bar(x, false)
