map. Also, because DenseMap allocates space for a large number of key/value
pairs (it starts with 64 by default), it will waste a lot of space if your keys
or values are large. Finally, you must implement a partial specialization of
DenseMapKeyInfo for the key that you want, if it isn't already supported. This
DenseMapInfo for the key that you want, if it isn't already supported. This
is required to tell DenseMap about two special marker values (which can never be
inserted into the map) that it needs internally.</p>
