A module holding named params blocks which other modules reuse with include.

defmodule MyApp.Params.Address do
  use Maru.Params.Schema

  params :basic do
    requires :city, String
    requires :zipcode, String
  end

  params :full do
    requires :address_line_1, String
    requires :city, String
    requires :zipcode, String
  end
end

params do ... end defines the anonymous block, named :default.

Options

• :reads - field names the given conditions of this schema read from the level it is included into, defaults to []
• :struct and :derive - define a struct from the declared params, same options as Maru.Params.TypeBuilder
