obuf

A simple Ruby object buffer. Use this if you need to temporarily store alot of serializable Ruby objects.

obuf = Obuf.new
5_000_000.times{  obuf.push(compute_some_object) } # no memory inflation
obuf.each do | stored_object | # objects are restored one by one
  # do something with stored_object
end

You can also write objects in one process, and recover them in another, using Obuf::Lens:

# In fork process
File.open('/tmp/output.bin', 'a') do |f|
  Obuf::Lens.new(f) << my_object
end

# In join process after forks completed
File.open('/tmp/output.bin', 'r') do |f|
  Obuf::Lens.new(f).each do | object_written_by_fork |
    puts object_written_by_fork.inspect
  end
end

The Lens is what is used under the hood in the main Obuf as well.
