Behaviour for message delivery adapters.

Anu ships with three adapters:

• Anu.Adapters.Meta - production adapter that sends messages via the Meta Cloud API
• Anu.Adapters.Local - development adapter that logs messages to the console
• Anu.Adapters.Test - test adapter that sends messages to the current process

Implementing a custom adapter

Implement the deliver/2 callback:

defmodule MyApp.CustomAdapter do
  @behaviour Anu.Adapter

  @impl true
  def deliver(message, client) do
    # Your delivery logic here; HTTP calls go through client.finch
    {:ok, %Anu.Response{id: "custom_123"}}
  end
end

Then use it on a client:

Anu.Client.new(adapter: MyApp.CustomAdapter, finch: MyApp.Finch)
