LiveView's Async Assigns

Notes

LiveView 0.20 ships with a new assign_async/3 function that makes adding an async assign on mount a breeze!

The assign_async/3 function returns a %AsyncResult{} struct that has an :ok?, :loading, :failed, and :result fields to help us display loading screens as well as failed and successful cases.

You can read more on the async assigns section of the docs.
