Enum nakadion::handler::HandlerAssignment

pub enum HandlerAssignment {
    Unspecified,
    EventType(EventTypeName),
    EventTypePartition(EventTypePartition),
}

Defines what a BatchHandler will receive.

This value should the same for the whole lifetime of the BatchHandler. "Should" because in the end it is the BatchHandlerFactory which returns BatchHandlers. But it is guaranteed that Nakadion will only pass events to a BatchHandler as defined by the DispatchStrategy.

Variants

Unspecified

Everything can be passed to the BatchHandler.

EventType(EventTypeName)

The BatchHandler will only receive events of the given event type but from any partition.

EventTypePartition(EventTypePartition)

The BatchHandler will only receive events of the given event type on the given partition.
