Detailed Description

template<typename StorageParam>
struct Bitpack< StorageParam >::FieldInfo

Information about a field within a Bitpack.

Fields are contiguous spans of bits and so have a lowest and highest bit position within the underlying Storage word.

Fields may be marked as constant to dissuade software from attempting to change their value. Do note, though, that any store of an underlying Storage word will also, necessarily, include the bits for constant Fields. It is likely generally more advisable to not mix constant and non-constant fields within the same Storage word or Bitpack.
