pub fn process(
  model model: dynamic.Dynamic,
  msg msg: dynamic.Dynamic,
  input_handler input_handler: fn(option.Option(model), msg) -> Result(
    #(model, view),
    error,
  ),

  model_to_json model_to_json: fn(model) -> json.Json,
  view_to_json view_to_json: fn(view) -> json.Json,
) -> json.Json

Take a model and a msg, put them through the input handler funtion, then return the result as a JSON object. Where:

If successed:

{
  model: output_model,
  view: output_view,
}

If failed:

{
  error: error,
}

For the model: nil, null, and undefined on Erlang, and undefined and null on JavaScript count as None.
