All events

// Execution event types
const (
	TypeUnknown EventType = iota
	TypeCall
	TypeLog
	TypeAccountInput
	TypeAccountOutput
	TypeTxExecution
	TypeBlockExecution
	TypeGovernAccount
	TypeBeginBlock
	TypeBeginTx
	TypeEnvelope
	TypeEndTx
	TypeEndBlock
)

Call

Fired whenever a contract is being called, even when called from another contract.

func (txe *TxExecution) Call(call *CallEvent, exception *errors.Exception) error {
	txe.Append(&Event{
		Header: txe.Header(TypeCall, EventStringAccountCall(call.CallData.Callee), exception),
		Call:   call,
	})
	return nil
}

Log

Fired from EVM opcode LOGX.

func (txe *TxExecution) Log(log *LogEvent) error {
	txe.Append(&Event{
		Header: txe.Header(TypeLog, EventStringLogEvent(log.Address), nil),
		Log:    log,
	})
	return nil
