Struct specs::storage::TrackChannels

pub struct TrackChannels {
    pub modify: EventChannel<ModifiedFlag>,
    pub insert: EventChannel<InsertedFlag>,

}

Fields

modify: EventChannel<ModifiedFlag>

Note: This does not include insertions, only when a component is changed after it has been added to an entity.

insert: EventChannel<InsertedFlag>

Insertions event channel.
