bn::ibitset class
#include <bn_bitset.h>

Base class of bn::bitset.

Can be used as a reference type for all bn::bitset containers.

Derived classes

template<int Size> class bitset: std::bitset like container.
class bitset_ref: ibitset implementation which manages an external elements array.

Public types

class reference: Proxy to allow to interact with individual bits of a ibitset.
using element_t = uint8_t: Element type alias.
