When will be avail full declaration of a new structs from hexrays?

i see will add a new structs like

class control_graph_t; // the result of structural analysis
class edge_mapper_t;
class node_bitset_t;

When will they be available for use ?
I mean expanded in the declaration

No such plans at the moment. These classes are intended for internal decompiler usage.

So, this is became challenge. Prove your reverse engineering skills by recreating missed types from hexrays binary :stuck_out_tongue_winking_eye:
