Subject: binaryparse: length in bytes of block definition?

Hi,

is there a way to derive the size in bytes of a custom
BinaryBlocker::Blocker definition?

class Foo < BinaryBlocker::Blocker
  has_one :offset, :int32
  has_one :length, :int32
end

Deriving the length would yield 8.

I've been using bit-struct for similar tasks, but it doesn't support
nesting class definition. However, bit-struct provides a
round_byte_length() for that purpose.

Is there an equivalent for it in binaryparse?

thanks,
- Markus
