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 digitalbits-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 digitalbits-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 /

type AssetStatSet 

type AssetStatSet map[assetStatKey]*assetStatValue

AssetStatSet represents a collection of asset stats

func (AssetStatSet) AddClaimableBalance 

func (s AssetStatSet) AddClaimableBalance(change ingest.Change) error

AddClaimableBalance updates the set to account for how a given claimable balance has changed. change must be a xdr.LedgerEntryTypeClaimableBalance type.

func (AssetStatSet) AddLiquidityPool 

func (s AssetStatSet) AddLiquidityPool(change ingest.Change) error

AddLiquidityPool updates the set to account for how a given liquidity pool has changed. change must be a xdr.LedgerEntryTypeLiqidityPool type.

func (AssetStatSet) AddTrustline
