Method ConsumeBytesAsString

src/test/fuzz/FuzzedDataProvider.h:136–145

Returns a std::string containing |num_bytes| of input data. Using this and |.c_str()| on the resulting string is the best way to get an immutable null-terminated C string. If fewer than |num_bytes| of data remain, returns a shorter std::string containing all of the data that's left.

// null-terminated C string. If fewer than |num_bytes| of data remain, returns
// a shorter std::string containing all of the data that's left.
inline std::string FuzzedDataProvider::ConsumeBytesAsString(size_t num_bytes) {
  static_assert(sizeof(std::string::value_type) == sizeof(uint8_t),
                "ConsumeBytesAsString cannot convert the data to a string.");

  num_bytes = std::min(num_bytes, remaining_bytes_);
  std::string result(
      reinterpret_cast<const std::string::value_type *>(data_ptr_), num_bytes);
  Advance(num_bytes);
  return result;
}

// Returns a std::string of length from 0 to |max_length|. When it runs out of
// input data, returns what remains of the input. Designed to be more stable
