Types ¶
type AddressTxsIndexer ¶
type AddressTxsIndexer interface {
// Accept is called when [txID] is accepted.
// Persists data about [txID] and what balances it changed.
// [inputUTXOs] are the UTXOs [txID] consumes.
// [outputUTXOs] are the UTXOs [txID] creates.
// If the error is non-nil, do not persist [txID] to disk as accepted in the VM
Accept(
txID ids.ID,
inputUTXOs []*lux.UTXO,
outputUTXOs []*lux.UTXO,
) error
// Read returns the IDs of transactions that changed [address]'s balance of [assetID].
// The returned transactions are in order of increasing acceptance time.
// The length of the returned slice <= [pageSize].
// [cursor] is the offset to start reading from.
Read(address []byte, assetID ids.ID, cursor, pageSize uint64) ([]ids.ID, error)
}
AddressTxsIndexer maintains information about which transactions changed the balances of which addresses. This includes both transactions that increase and decrease an address's balance. A transaction is said to change an address's balance if either is true: 1) A UTXO that the transaction consumes was at least partially owned by the address. 2) A UTXO that the transaction produces is at least partially owned by the address.
func NewIndexer ¶
func NewIndexer( db database.Database, log log.Logger, metricsNamespace string, metricsRegisterer metric.Registerer, allowIncompleteIndices bool, ) (AddressTxsIndexer, error)
NewIndexer returns a new AddressTxsIndexer. The returned indexer ignores UTXOs that are not type secp256k1fx.TransferOutput.
func NewNoIndexer ¶
func NewNoIndexer(db database.Database, allowIncomplete bool) (AddressTxsIndexer, error)
