The whole graph. The suggested interface is to only use lookupHeapGraph, as the internal representation may change. Nevertheless, we export it here: Sometimes the user knows better what he needs than we do.

data HeapGraphEntry a #

For heap graphs, i.e. data structures that also represent sharing and cyclic structures, these are the entries. If the referenced value is Nothing, then we do not have that value in the map, most likely due to exceeding the recursion bound passed to buildHeapGraph.

Besides a pointer to the stored value and the closure representation we have a slot for arbitrary data, for the user's convenience.
