Struct dittolive_ditto::store::collections::event::CollectionsEvent

pub struct CollectionsEvent {
    pub is_initial: bool,
    pub collections: Vec<Collection>,
    pub old_collections: Vec<Collection>,
    pub insertions: Box<[usize]>,
    pub deletions: Box<[usize]>,
    pub updates: Box<[usize]>,
    pub moves: Vec<LiveQueryMove>,
}

Provides information about the changes that have occurred in relation to an event delivered when observing the collections in a DittoStore. It contains information about the collections that are known about as well as the collections that were previously known about in the previous event, along with information about what collections have been inserted, deleted, updated, or moved since the last event.

Fields

collections: Vec<Collection>

old_collections: Vec<Collection>

insertions: Box<[usize]>

deletions: Box<[usize]>

updates: Box<[usize]>

moves: Vec<LiveQueryMove>
