Is there a way to directly copy a string to mmap_sink?

[L-Super]

When the string is large, iterating and assigning values becomes inefficient.

  std::string data{"word"};
  try {
    mio::mmap_sink mmap(path, 10);
    for (int i = 0; i < data.size(); ++i) {
      mmap[i] = data[i];
    }
  } catch (std::system_error e) {
    std::cout<<"error: "<<e.what()<<"\n";
  }

memcpy(&mmap[0], data.cstr(), data.size)

memcpy(&mmap[0], data.cstr(), data.size)

Thanks! I found that std::copy is also a good way.
