Details:

With TypedEnum now you can have T::Enum version of Rails Enum

  sig { returns(T.nilable(Wizard::House)) }
  def typed_house; end

  sig { params(value: T.nilable(Wizard::House)).void }
  def typed_house=(value); end

TypedParams is a generalized version of fetch_typed & require_typed, that allows parsing nested params structure

class MyCoolController < ApplicationController
  class MyActionParams < T::Struct
    const :id, T.nilable(Integer)
    const :show, T.nilable(T::Boolean)
    const :wands, T::Array[Integer]
  end
  sig { void }
  def my_action
    typed_params = TypedParams[MyActionParams].new.extract!(params)
    # T.reveal_type(typed_params) => MyActionParams
    # T.reveal_type(typed_params.show) => T.nilable(T::Boolean)
  end
end
