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: cached_value.rb
    path of file: ./repos/i18n-tasks/lib/i18n/tasks/concurrent
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module I18n::Tasks::Concurrent
  # A thread-safe m
    
    def get
      return get_result_volatile unless get_result_volatile == NULL

      @mutex.synchronize do
        next unless get_result_volatile == NULL

        set_result_volatile @computation.call
        @computation = nil
      end
      get_result_volatile
    end
