Enum Op 

pub enum Op {
    Set,
    Insert,
    Delete,
    Move,
}

What kind of change was announced. A persistence layer needs this to choose between an INSERT, an UPDATE and a DELETE; the UI does not care, which is why it rides alongside the path rather than inside it.

Variants

Set

One field was written.

Insert

A row entered the collection.

Delete

A row left it.

Move

The collection’s order changed.
