Types ¶
type Tracer ¶
type Tracer struct {
// contains filtered or unexported fields
}
Tracer provides an implementation of Tracer that evaluates a Javascript function for each VM execution step.
func New ¶
New instantiates a new tracer instance. code specifies a Javascript snippet, which must evaluate to an expression returning an object with 'step', 'fault' and 'result' functions.
func (*Tracer) CaptureEnd ¶
CaptureEnd is called after the call finishes to finalize the tracing.
func (*Tracer) CaptureFault ¶
func (jst *Tracer) CaptureFault(env *vm.EVM, pc uint64, op vm.OpCode, gas, cost uint64, memory *vm.Memory, stack *vm.Stack, contract *vm.Contract, depth int, fallbackFlag vm.ForFallback, err error) error
Sooyeon LEE 20190410 add argument CaptureFault implements the Tracer interface to trace an execution fault while running an opcode.
func (*Tracer) CaptureStart ¶
func (jst *Tracer) CaptureStart(from common.Address, to common.Address, create bool, input []byte, gas uint64, value *big.Int) error
CaptureStart implements the Tracer interface to initialize the tracing operation.
func (*Tracer) CaptureState ¶
func (jst *Tracer) CaptureState(env *vm.EVM, pc uint64, op vm.OpCode, gas, cost uint64, memory *vm.Memory, stack *vm.Stack, contract *vm.Contract, depth int, fallbackFlag vm.ForFallback, err error) error
Sooyeon LEE 20190410 add parameter fallbackFlag CaptureState implements the Tracer interface to trace a single step of VM execution.
