pub enum Diff<T> {
Change(T),
Remove,
Keep,
Add(T),
}
Expand description
The difference between two iterator elements.
Variants
Change(T)
Changed item. The element of the left-hand side iterator differs from that of the right-hand side iterator. The new element is returned contained in this variant.
Remove
Removed item. The element of the left-hand side iterator is not present in the right-hand side iterator.
Keep
Kept item. The element of the left-hand side iterator is the same as the element of the right-hand side iterator.
Add(T)
Added item. The left-hand side iterator does not contain this element of the right-hand side iterator.
