Protocol for encoding custom data structures to TOON format.

This protocol allows you to define how your custom structs should be encoded to TOON format, similar to Jason.Encoder.

Example

defmodule User do
  @derive {Toon.Encoder, only: [:name, :email]}
  defstruct [:id, :name, :email, :password_hash]
end

Or implement the protocol manually:

defimpl Toon.Encoder, for: User do
  def encode(user, opts) do
    %{
      "name" => user.name,
      "email" => user.email
    }
    |> Toon.Encode.encode!(opts)
  end
end
