Functions

func EncodeOfferId

func EncodeOfferId(id uint64, typ OfferIDType) int64

EncodeOfferId creates synthetic offer ids to be used by trade resources

This is required because aiblocks-core does not allocate offer ids for immediately filled offers, while clients expect them for aggregated views.

The encoded value is of type int64 for sql compatibility. The 2nd bit is used to differentiate between aiblocks-core offer ids and operation ids, which are toids.

Due to the 2nd bit being used, the largest possible toid is: 0011111111111111111111111111111100000000000000000001000000000001 \ ledger /\ transaction /\ op /
