Fields

data: Option<Rc<T>>

A callback is issued for each delta, allowing the user to store whatever info they want about the change. This is an Option for the sake of filtering—we can’t omit the node entirely (or the processing that generated it), as we could screw up the history graph. Instead, we make the contents None for all nodes from a filtered-out commit.

previous: Option<Link<HistoryNode<T>>>

What’s the previous change?
