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: resource_client_request.rb
    path of file: ./repos/aws-sdk-ruby/build_tools/aws-sdk-code-generator/lib/aws-sdk-code-generator/rbs
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module AwsSdkCodeGenerator
  module RBS
    class ResourceClientRequest
      include Helper

      attr_reader :method_name
      att
    
      def build_method_signature
        MethodSignature.new(
          method_name: method_name,
          overloads: [
            "(#{arguments}) -> #{returns}",
            "(#{@include_required ? "" : "?"}Hash[Symbol, untyped]) -> #{returns}"
          ]
        )
      end
