Id of the next message.

promiseMap: Map<number, PromiseWorkerResponseWrapper<Worker, Response>> = ...
+

The promise map.

+
  • key: This is the message Id of each submitted task.
  • value: An object that contains the worker, the resolve function and the reject function.

When we receive a message from the worker we get a map entry and resolve/reject the promise based on the message.
