IdAddedOrRemoved

The IdAddedOrRemoved type describes a change made to an Id in either the tabular of keyed-value part of the Store.

1 | -1

This type is used in other types like ChangedTableIds, ChangedRowIds, ChangedCellIds, and ChangedValueIds.

It is a simple number: a 1 indicates that a given Id was added to the Store during a transaction, and a -1 indicates that it was removed.
