Functions ¶
func ColorPrintf ¶
func EstimateTargetBlocknumber ¶
Roughly estimate a block number by target timestamp (might be off by a lot)
func FindBlockRange ¶ added in v0.3.0
func FindBlockRange(client *ethclient.Client, blockHeight int, date string, hour int, min int, length string) (startBlock int64, endBlock int64, err error)
GetBlockRangeFromArguments returns start and end blocks for a given block or date range. startBlock is first block at or after the given time, endBlock is the last before the given end time.
func GetBlocks ¶ added in v0.5.2
func GetBlocks(blockChan chan<- *types.Block, client *ethclient.Client, startBlock int64, endBlock int64, concurrency int)
GetBlocks is a fast block query pipeline. It queries blocks concurrently and pushes it into a channel for processing.
func GetErc20TokensInUnit ¶ added in v0.3.3
func GetErc20TokensInUnit(numTokens *big.Int, addrDetail addressdetail.AddressDetail) (amount *big.Float, symbol string)
func GetFirstBlockHeaderAtOrAfterTime ¶
func GetFirstBlockHeaderAtOrAfterTime(client *ethclient.Client, targetTime time.Time) (header *types.Header, err error)
GetBlockHeaderAtTimestamp returns the header of the first block at or after the timestamp. If timestamp is after latest block, then return latest block. This function is a bit messy, but works. Improvements to this approach are welcome.
func GetTxSender ¶
func GetTxSender(tx *types.Transaction) (from common.Address, err error)
func IsBigIntZero ¶
func PrintBlock ¶
func WeiBigIntToEthString ¶ added in v0.3.2
// Returns bigint wei amount as comma-separated, human-readable string (eg. 1,435,332.71)
func WeiUintToEth ¶ added in v0.3.2
