33/* @todo
34 * We have two ways of saving/loading states.
35 *
36 * First which is being used atm, just pure saving/loading of structures.
37 * The drawback is we have to deal with all the pointers around those structures,
38 * we'd have to update this code if we'd change state tracking.
39 * On the bright side it's fast, though it's not really needed as it's not that often operation.
40 * It could also worth to split those functions into appropriate parts,
41 * similar to the way context creation is being done.
42 *
43 * Second way would be to implement full dispatch api table and substitute diff_api during saving/loading.
44 * Then if we implement that api in a similar way to packer/unpacker with a change to store/load
45 * via provided pSSM handle instead of pack buffer,
46 * saving state could be done by simple diffing against empty "dummy" context.
47 * Restoring state in such case would look like unpacking commands from pSSM instead of network buffer.
48 * This would be slower (who cares) but most likely will not require any code changes to support in future.
49 * We will reduce amount of saved data as we'd save only changed state parts, but I doubt it'd be that much.
50 * It could be done for the first way as well, but requires tons of bit checks.
