Struct EventId 

pub struct EventId<E>
where
    E: Event,
{
    pub id: usize,
    /* private fields */
}

An EventId uniquely identifies an event stored in a specific World.

An EventId can among other things be used to trace the flow of an event from the point it was sent to the point it was processed. EventIds increase monotonically by send order.

Fields

id: usize

Uniquely identifies the event associated with this ID.
