Module: BinData::BitAligned

Defined in:
lib/bindata/alignment.rb

Overview

A monkey patch to force byte-aligned primitives to become bit-aligned. This allows them to be used at non byte based boundaries.

class BitString < BinData::String
  bit_aligned
end

class MyRecord < BinData::Record
  bit4       :preamble
  bit_string :str, length: 2
end

Defined Under Namespace
