Function fill

native/thirdpart/flatbuffers/flatbuffers.h:1048–1051

fill() is most frequently called with small byte counts (<= 4), which is why we're using loops rather than calling memset.

  // fill() is most frequently called with small byte counts (<= 4),
  // which is why we're using loops rather than calling memset.
  void fill(size_t zero_pad_bytes) {
    make_space(zero_pad_bytes);
    for (size_t i = 0; i < zero_pad_bytes; i++) cur_[i] = 0;
  }

  // Version for when we know the size is larger.
  // Precondition: zero_pad_bytes > 0
