Defined at line 991 of file ../../third_party/github.com/google/emboss/src/runtime/cpp/emboss_memory_util.h
BitBlock is a view of a short, fixed-size sequence of bits somewhere in
memory. Big- and little-endian values are handled by BufferType, which is
typically BigEndianByteOrderer
<ContiguousBuffer
<
...>> or
LittleEndianByteOrderer
<ContiguousBuffer
<
...>>.
BitBlock is implemented such that it always reads and writes its entire
buffer; unlike ContiguousBuffer for bytes, there is no way to modify part of
the underlying data without doing a read-modify-write of the full value.
This sidesteps a lot of weirdness with converting between bit addresses and
byte addresses for big-endian values, though it does mean that in certain
cases excess bits will be read or written, particularly if care is not taken
in the .emb definition to keep `bits` types to a minimum size.

ValueType ReadUInt ()BitBlock clients must read or write the entire BitBlock value as an
unsigned integer. OffsetBitBlock can be used to extract a portion of the
value via shift and mask, and individual view types such as IntView or
BcdView are expected to convert ValueType to/from their desired types.
