Enum LiveQueryEvent 

pub enum LiveQueryEvent {
    Initial,
    Update {
        old_documents: Vec<BoxedDocument>,
        insertions: Box<[usize]>,

}

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

Use pending_op.observe_local(...) to receive LiveQueryEvents describing document changes.

Describes the different types of event that you can receive when dealing with live queries.

Variants

Initial

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

The first event that will be delivered and it will only be delivered once.

Update

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

It contains information about the set of documents that previously matched the query before the update, along with information about what documents have been inserted, deleted, updated, or moved, as part of the set of matching documents.
