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: timer_tracer.rb
    path of file: ./repos/gitlabhq/lib/gitlab/graphql/tracers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
  module Graphql
    module Tracers
      # This
    
        def trace(key, data)
          start_time = ::Gitlab::Metrics::System.monotonic_time

          yield
        ensure
          data[:duration_s] = ::Gitlab::Metrics::System.monotonic_time - start_time
        end
