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: health.rb
    path of file: ./repos/diplomat/lib/diplomat
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Diplomat
  # Methods for interacting with the Consul health API endpoint
  class Health < Diplomat::RestClient
    @access_methods = %i[node checks service state
                         an
    
    def checks(s, options = {})
      custom_params = []
      custom_params << use_named_parameter('dc', options[:dc]) if options[:dc]
      custom_params << use_named_parameter('filter', options[:filter]) if options[:filter]

      ret = send_get_request(@conn, ["/v1/health/checks/#{s}"], options, custom_params)
      JSON.parse(ret.body).map { |check| OpenStruct.new check }
    end
