Sticky attributes

Sticky attributes are similar to regular attributes except they will be copied to any message immediately or subsequently sent as a result of the original message being processed.
These can be sent by specifying a value for stickyAttributes
await bus.send(
  new ChargeCreditCard(),
  {
    stickyAttributes: {
      ip: '229.40.202.156',
      attempt: 0,
      automatic: true
    }
  }
)
Sticky attributes can be accessed using the stickyAttribtues of the second parameter of a handler.
import { MessageAttributes } from '@node-ts/bus-messages'
​
await Bus.configure()
  .withHandler(
    ChargeCreditCard,
    async (_: ChargeCreditCard, { stickyAttributes }: MessageAttributes) => console.log(attributes)
  )
  .initialize()
