Types

type Log

type Log struct {
	// Consensus fields:
	// address of the contract that generated the event
	Address types.Address `json:"address" gencodec:"required"`
	// list of topics provided by the contract.
	Topics []types.Hash `json:"topics" gencodec:"required"`
	// supplied by the contract, usually ABI-encoded
	Data []byte `json:"data" gencodec:"required"`

	// Derived fields. These fields are filled in by the node
	// but not secured by consensus.
	// block in which the transaction was included
	BlockNumber uint64 `json:"blockNumber"`
	// hash of the transaction
	TxHash types.Hash `json:"transactionHash" gencodec:"required"`
	// index of the transaction in the block
	TxIndex uint `json:"transactionIndex" gencodec:"required"`
	// hash of the block in which the transaction was included
	BlockHash types.Hash `json:"blockHash"`
	// index of the log in the receipt
	Index uint `json:"logIndex" gencodec:"required"`

	// The Removed field is true if this log was reverted due to a chain reorganisation.
	// You must pay attention to this field if you receive logs through a filter query.
	Removed bool `json:"removed"`
}

Log represents a contract log event. These events are generated by the LOG opcode and stored/indexed by the node.

func (*Log) DecodeRLP

func (l *Log) DecodeRLP(s *rlp.Stream) error

DecodeRLP implements rlp.Decoder.

func (*Log) EncodeRLP

func (l *Log) EncodeRLP(w io.Writer) error

EncodeRLP implements rlp.Encoder.

type LogForStorage

type LogForStorage Log

LogForStorage is a wrapper around a Log that flattens and parses the entire content of a log including non-consensus fields.

func (*LogForStorage) DecodeRLP

func (l *LogForStorage) DecodeRLP(s *rlp.Stream) error

DecodeRLP implements rlp.Decoder.

func (*LogForStorage) EncodeRLP

func (l *LogForStorage) EncodeRLP(w io.Writer) error

EncodeRLP implements rlp.Encoder.
