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: user.rb
    path of file: ./repos/rails-mini-profiler/lib/rails_mini_profiler
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module RailsMiniProfiler
  class U
    
    def find_current_user
      return if Rails.env.production?

      user = RailsMiniProfiler.configuration.user_provider.call(@env)
      User.current_user = user
      user
    end
