Functions

func NewDeltaLoggerProxy 

func NewDeltaLoggerProxy(db state.StateDB, sink *DeltaLogSink) state.StateDB

NewDeltaLoggerProxy wraps the given StateDB with the delta logger.

func NewLoggerProxy 

func NewLoggerProxy(db state.StateDB, log logger.Logger, output chan string, wg *sync.WaitGroup) state.StateDB
