Required methods

fn diff_equal<V: ?Sized>(&mut self, a: &V, b: &V) where
    V: Diff, 

The sets contain a and b which compare as equal. Check them for differences.

fn only_in_left<V: ?Sized>(&mut self, a: &V) where
    V: Diff, 

Value a is only in the left-hand set.

fn only_in_right<V: ?Sized>(&mut self, b: &V) where
    V: Diff, 

Value b is only in the right-hand set.

fn end(self) -> Result<Self::Ok, Self::Err>

We've reached the end of the sets.
