<p>It’s used for sorting nodes (ascending for asks, descending for bids)

in the lower bits.</p>

<p>The <code>seq_num</code> that’s passed should monotonically increase. It’s used to choose

the ordering number such that orders placed later for the same price data

are ordered after earlier orders.</p>
