# File lib/fauna/client_logger.rb, line 21
def self.show_request_result(request_result)
  rr = request_result
  logged = ''

  logged << "Fauna #{rr.method.to_s.upcase} /#{rr.path}#{query_string_for_logging(rr.query)}\n"
  logged << "  Credentials: #{rr.auth}\n"
  if rr.request_content
    logged << "  Request JSON: #{indent(FaunaJson.to_json_pretty(rr.request_content))}\n"
  end
  logged << "  Response headers: #{indent(FaunaJson.to_json_pretty(rr.response_headers))}\n"
  logged << "  Response JSON: #{indent(FaunaJson.to_json_pretty(rr.response_content))}\n"
  logged << "  Response (#{rr.status_code}): Network latency #{(rr.time_taken * 1000).to_i}ms"
