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: attached_klass.rb
    path of file: ./repos/rubex/lib/rubex/ast/top_statement/klass
    
    the code of the file until where you have to start completion: module Rubex
  module AST
    module TopStatement
      class A
    
        def write_data_type_t_struct(code)
          decl = ''
          decl << "static const rb_data_type_t #{@data_type_t} = {\n"
          decl << "  \"#{@name}\",\n"
          decl << "  {0, #{@dealloc_c_func.c_name}, #{@memcount_c_func.c_name},\n"
          decl << "  0}, 0, 0, RUBY_TYPED_FREE_IMMEDIATELY\n"
          decl << "};\n"

          code << decl
          code.new_line
        end
