C++ often uses [`std::vector<uint8_t>`](https://en.cppreference.com/w/cpp/container/vector) to represent Data. Use `copy()` to duplicate the bytes into a new owning `ArrayBuffer`.
```cpp
std::vector<uint8_t> data;
auto buffer = ArrayBuffer::copy(data);
/* convert back to vector would be a copy. */
```
Use `move()` to transfer a vector's storage without an extra copy.
```cpp
std::vector<uint8_t> data;
auto buffer = ArrayBuffer::move(std::move(data));
```
