WebExposes class std::vector::reference as a method of accessing individual bits. In particular, objects of this class are returned by operator [] by value. Does not use std::allocator_traits::construct to construct bit values. Does not guarantee that different elements in the same container can be modified concurrently by different threads. WebFirst, note that the bit vector struct contains a pointer variable to the unsigned char array. That means when you create a new bit vector, there are two allocations: the unsigned char array and the bit vector struct value. Second, one of the things that makes this task difficult is that there are three layers of abstraction.
