}

func (*Indexer) DoDBUpdates

func (indexer *Indexer) DoDBUpdates(wg *sync.WaitGroup, txDataChan chan *DBData, blockEventsDataChan chan *BlockEventsDBData, dbChainID uint)

doDBUpdates will read the data out of the db data chan that had been processed by the workers if this is a dry run, we will simply empty the channel and track progress otherwise we will index the data in the DB. it will also read rewars data and index that.

func (*Indexer) ProcessBlocks

func (indexer *Indexer) ProcessBlocks(wg *sync.WaitGroup, failedBlockHandler core.FailedBlockHandler, blockRPCWorkerChan chan core.IndexerBlockEventData, blockEventsDataChan chan *BlockEventsDBData, txDataChan chan *DBData, chainID uint, blockEventFilterRegistry BlockEventFilterRegistries)

This function is responsible for processing raw RPC data into app-usable types. It handles both block events and transactions. It parses each dataset according to the application configuration requirements and passes the data to the channels that handle the parsed data.

func (*Indexer) RegisterCustomBeginBlockEventParser

func (indexer *Indexer) RegisterCustomBeginBlockEventParser(eventKey string, parser parsers.BlockEventParser)

func (*Indexer) RegisterCustomEndBlockEventParser

func (indexer *Indexer) RegisterCustomEndBlockEventParser(eventKey string, parser parsers.BlockEventParser)

func (*Indexer) RegisterCustomMessageParser

func (indexer *Indexer) RegisterCustomMessageParser(messageKey string, parser parsers.MessageParser)

func (*Indexer) RegisterCustomModels

func (indexer *Indexer) RegisterCustomModels(models []any)

func (*Indexer) RegisterCustomModuleBasics

func (indexer *Indexer) RegisterCustomModuleBasics(basics []module.AppModuleBasic)

func (*Indexer) RegisterMessageTypeFilter

func (indexer *Indexer) RegisterMessageTypeFilter(filter filter.MessageTypeFilter)

type PostIndexCustomMessageDataset

type PostIndexCustomMessageDataset struct {
	Config         config.IndexConfig
	DB             *gorm.DB
	DryRun         bool
	IndexedDataset *[]dbTypes.TxDBWrapper
	MessageParser  map[string]models.MessageParser
	IndexedBlock   models.Block
}

type PostSetupCustomDataset

type PostSetupCustomDataset struct {
	Config config.IndexConfig
	DB     *gorm.DB
}

type PostSetupDataset

type PostSetupDataset struct {
	Config      *config.IndexConfig
	DryRun      bool
	ChainClient *client.ChainClient
}

DB is not safe to add here just yet, since the index command in cmd/ defers a close of the DB connection Maybe the defer should be removed?

type PreExitCustomDataset

type PreExitCustomDataset struct {
	Config config.IndexConfig
	DB     *gorm.DB
	DryRun bool
}
