Enum Remove 

pub enum Remove<C>
where
    C: ?Sized,
{
    // some variants omitted
}

A TargetedEvent which removes component C from an entity when sent. The component is dropped and cannot be recovered.

Any handler which listens for Remove<C> will run before the component is removed. Remove<C> has no effect if the target entity does not exist or the event is consumed before it finishes broadcasting.

This type behaves like a unit struct. Use Remove::<C> to instantiate the type.

Examples

world.send_to(target, Remove::<C>);
