Struct Diff 

pub struct Diff(/* private fields */);

A difference over the layers below it, as JSON: an object is a node, by id, and anything else is a setting.

{ "Views": { "Account_ListView": { "Columns": { "opening": { "Index": -1 } } } } }

A node that this difference itself creates has "$new": true.
