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: buffer.rb
    path of file: ./repos/truffleruby/lib/truffle/truffle/ffi_backend
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
# truffleruby_primitives: true

    def self.new(type, count = 1, clear = true)
      # Do not set autorelease mode
      buffer = allocate
      buffer.send(:initialize, type, count, clear)

      if block_given?
        begin
          yield buffer
        ensure
          buffer.free
        end
