Worker

Workers are any type that keep track of the current EventLoop.

Worker is a simple protocol and can be conformed to if the context can return (by means of a computed property) or contain an EventLoop.

There are three primary Workers that you can use to access the EventLoop and it's queue or context.

• Request can be used, usually from within a Route
• EventLoop is itself a worker to ensure the extensions and consumers of Worker can be used, too.
• DispatchQueue is a worker that will return a new and clean EventLoop based on the current DispatchQueue
