You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: past_move_stat_value.rb
    path of file: ./repos/poke-api-v2/lib/poke_api/move
    
    the code of the file until where you have to start completion: module PokeApi
  class Move
    # PastMoveStatValue object handling all data fetched from /move for past_values
    class PastMoveStatValue
      include Assignmen
    
      def initialize(data)
        @accuracy = data[:accuracy]
        @effect_chance = data[:effect_chance]
        @power = data[:power]
        @pp = data[:pp]
        @effect_entries = assign_list(data: data[:effect_entries], klass: Common::VerboseEffect)
        @type = try_to_assign(data: data[:type], klass: Type)
        @version_group = try_to_assign(data: data[:version_group], klass: VersionGroup)
      end
