Enum Write 

pub enum Write {
    Append,
    Update,
    Delete,
}

What an Insert’s source means for the table.

Variants

Append

The rows are added to the table.

Update

The rows are the whole table afterwards, and one more column after the table’s says which of them the statement changed, so it can count them and return them.

Delete

The rows are the table as it was, and the column after the table’s says which of them the statement deletes. The table keeps the rest.
