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: index_violation_detector.rb
    path of file: ./repos/rails_event_store/ruby_event_store-active_record/lib/ruby_event_store/active_record
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module RubyEventStore
  module ActiveRecord
    class IndexViolationDetector
      def initializ
    
      def initialize(event_store_events, event_store_events_in_streams)
        @postgres_pkey_error = "Key (event_id)".freeze
        @postgres_index_error = "Key (stream, event_id)".freeze
        @mysql5_pkey_error = "for key 'index_#{event_store_events}_on_event_id'".freeze
        @mysql8_pkey_error = "for key '#{event_store_events}.index_#{event_store_events}_on_event_id'".freeze
        @mysql5_index_error = "for key 'index_#{event_store_events_in_streams}_on_stream_and_event_id'".freeze
        @mysql8_index_error =
          "for key '#{event_store_events_in_streams}.index_#{event_store_events_in_streams}_on_stream_and_event_id'"
            .freeze
        @sqlite3_pkey_error = "constraint failed: #{event_store_events}.event_id".freeze
        @sqlite3_index_error =
          "constraint failed: #{event_store_events_in_streams}.stream, #{event_store_events_in_streams}.event_id".freeze
