	// Nethermind reports the change in memory on step earlier than others. E.g.

	// Nethermind reports the change in memory on step earlier than others. E.g.
	// MSTORE shows the _new_ memory, besu/geth shows the old memory until the next op.
	// Unfortunately, nethermind also "forgets" the memsize when an error occurs, reporting
	// memsize zero (see testdata/traces/stackUnderflow_nonzeroMem.json). So we use
	// ClearMemSize instead
	ClearMemSizeOnExpand = true

	ClearReturndata = true

Functions

func CompareFiles 

func CompareFiles(vms []Evm, readers []io.Reader) (bool, int, string)

CompareFiles returns true if the files are equal, along with the number of line s compared

func CustomMarshal 

func CustomMarshal(log *opLog) []byte

CustomMarshal writes a logger.Structlog element into a concise json format. OBS! This output format will omit all stack element except the last 6 items.

func JsonMarshal 

func JsonMarshal(log *logger.StructLog) []byte

func NewJsonlScanner 

func NewJsonlScanner(clientName string, input io.Reader, errOut io.Writer) *jsonlScanner
