Enum specs::prelude::ComponentEvent

source · [−]

pub enum ComponentEvent {
    Inserted(Index),
    Modified(Index),
    Removed(Index),
}

Expand description

Component storage events received from a FlaggedStorage or any storage that implements Tracked.

Variants

`Inserted(Index)`

An insertion event, note that a modification event will be triggered if the entity already had a component and had a new one inserted.

`Modified(Index)`

A modification event, this will be sent any time a component is accessed mutably so be careful with joins over &mut storages as it could potentially flag all of them.

`Removed(Index)`

A removal event.
