Typed struct to help modeling strong references.

Example

defmodule MyApp.ReplyRef do
  use Ash.TypedStruct

  typed_struct do
    field :root, AshAtproto.StrongRef, allow_nil?: false
    field :parent, AshAtproto.StrongRef, allow_nil?: false
  end
end

defmodule MyApp.BskyPost do
  use Ash.Resource,
    domain: MyApp.Mixtapes,
    data_layer: AshAtproto.DataLayer

  attributes do
    attribute :rkey, :string, primary_key?: true, allow_nil?: false
    attribute :repo_did, :string, primary_key?: true, allow_nil?: false

    attribute :uri, :string, primary_key?: true, allow_nil?: false
    attribute :cid, :string, allow_nil?: false

    attribute :text, :string
    attribute :reply, MyApp.Atproto.ReplyRef
  end

  relationships do
    has_one :parent_reply, __MODULE__ do
      manual AshAtproto.Relationships.ParentPost
      relationship_context %{path_to_strong_ref: [:reply, :parent]}
      description "The parent of this post."
    end
  end
end
