Functions ¶
func LoadFirstBlock ¶
LoadFirstBlock loads the first indexed block, returns -1 if db is empty
func LoadLastBlock ¶
LoadLastBlock returns the latest indexed block number, returns -1 if db is empty
func TxIndexKey ¶
TxIndexKey returns the key for db entry: `(block number, tx index) -> tx hash`
Types ¶
type KVIndexer ¶
type KVIndexer struct {
// contains filtered or unexported fields
}
KVIndexer implements a eth tx indexer on a KV db.
func NewKVIndexer ¶
NewKVIndexer creates the KVIndexer
func (*KVIndexer) FirstIndexedBlock ¶
FirstIndexedBlock returns the first indexed block number, returns -1 if db is empty
func (*KVIndexer) GetByBlockAndIndex ¶
func (kv *KVIndexer) GetByBlockAndIndex(blockNumber int64, txIndex int32) (*ethermint.TxResult, error)
GetByBlockAndIndex finds eth tx by block number and eth tx index
func (*KVIndexer) GetByTxHash ¶
GetByTxHash finds eth tx by eth tx hash
func (*KVIndexer) IndexBlock ¶
IndexBlock index all the eth txs in a block through the following steps: - Iterates over all of the Txs in Block - Parses eth Tx infos from cosmos-sdk events for every TxResult - Iterates over all the messages of the Tx - Builds and stores a indexer.TxResult based on parsed events for every message
func (*KVIndexer) LastIndexedBlock ¶
LastIndexedBlock returns the latest indexed block number, returns -1 if db is empty
