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: fetch_events.rb
    path of file: ./repos/rails_event_store/ruby_event_store-rspec/lib/ruby_event_store/rspec
    
    the code of the file until where you have to start completion: # frozen_string
    
      def call
        raise MissingEventStore if event_store.nil?
        events = event_store.read
        events = events.stream(stream_name) if stream_name
        events = events.from(start) if start
        events
      end
