Types

type ComparisonOperator

type ComparisonOperator int32

ComparisonOperator is an enumeration of topic comparison operators. ENUM(and,or)

const (
	// ComparisonOperatorAnd is a ComparisonOperator of type And.
	ComparisonOperatorAnd ComparisonOperator = iota
	// ComparisonOperatorOr is a ComparisonOperator of type Or.
	ComparisonOperatorOr
)

func ParseComparisonOperator

func ParseComparisonOperator(name string) (ComparisonOperator, error)

ParseComparisonOperator attempts to convert a string to a ComparisonOperator

func (ComparisonOperator) String

func (x ComparisonOperator) String() string

String implements the Stringer interface.

type LogResponse

type LogResponse struct {
	Address          common.Address
	BlockNumber      uint64 `etherscan:"blockNumber,hex"`
	Data             []byte
	GasPrice         *big.Int  `etherscan:"gasPrice,hex"`
	GasUsed          *big.Int  `etherscan:"gasUsed,hex"`
	LogIndex         uint32    `etherscan:"logIndex,hex"`
	Timestamp        time.Time `etherscan:"timeStamp,hex"`
	Topics           []common.Hash
	TransactionHash  common.Hash `etherscan:"transactionHash"`
	TransactionIndex uint32      `etherscan:"transactionIndex,hex"`
}

LogResponse contains information on an ethereum log.

type LogsBlockParam

type LogsBlockParam struct {
	Number uint64

}

LogsBlockParam contain block-related parameters.

type LogsClient

type LogsClient struct {
	API *httpapi.APIClient
}

LogsClient is the client for logs related actions.

func (*LogsClient) GetLogs

func (c *LogsClient) GetLogs(ctx context.Context, req *LogsRequest) ([]LogResponse, error)

GetLogs provides an alternative to the native eth_getLogs.

type LogsRequest
