code: public void copyBytesTo(byte[] dest, int destOffset) {
      Utils.checkIndex(destOffset, dest.length);
      dest[destOffset] = options;
    }
docs: Copies the byte representations of the {@code TraceOptions} into the {@code dest} beginning at
  the {@code destOffset} offset.
  
  <p>Equivalent with (but faster because it avoids any new allocations):
  
  <pre>{@code
  System.arraycopy(getBytes(), 0, dest, destOffset, TraceOptions.SIZE);
  }</pre>
  
  @param dest the destination buffer.
  @param destOffset the starting offset in the destination buffer.
  @throws NullPointerException if {@code dest} is null.
  @throws IndexOutOfBoundsException if {@code destOffset+TraceOptions.SIZE} is greater than
  {@code dest.length}.
