Event

Event Struct

A struct of Cizen.Event has the following four fields:

• :id an unique ID for the event.
• :body a struct.
• :source_saga_id a saga ID of the source of the event.
• :source_saga a saga struct the source of the event.

Creating a Event

You can create an event by using Cizen.Event.new/2 like this:

event = Cizen.Event.new(nil, %PushMessage{to: "user A"})

The first argument is the source saga ID or nil, and the second argument is the event body.

Dispatching Event

With Dispatcher

Cizen.Dispatcher.dispatch(
  Cizen.Event.new(nil, %PushMessage{to: "user A"})
)

With Dispatch Effect

use Cizen.Effectful
use Cizen.Effects

handle fn id ->
  dispatched_event = perform id, %Dispatch{
    body: %PushMessage{to: "user A"}
  }
end

Requestive Event

You can make your event requestive. See Cizen.Request.defresponse/3.
