pub enum Diff<T> {
    Same,
    Born(T),
    Changed(T, T),
    Died(T),
}

Expand description

Diff type for specifying a change (or not).

Variants

`Same`

Both sides are the same.

`Born(T)`

Left (pre, source) side doesn’t include value, right side (post, destination) does.

`Changed(T, T)`

Both sides include data; it chaged value between them.

`Died(T)`

Left (pre, source) side does include value, right side (post, destination) does not.
