Struct ExecutionTracer 

pub struct ExecutionTracer { /* private fields */ }

A tracer that traces opcode and syscall execution step-by-step.

Implementations

impl ExecutionTracer

pub fn new(config: ExecutionTracerConfig) -> Self

Create a new ExecutionTracer instance.

pub fn collect_trace(self) -> ExecutionTrace

Collect the traces and return them.

Trait Implementations

impl Clone for ExecutionTracer

fn clone(&self) -> ExecutionTracer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecutionTracer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ExecutionTracer

fn default() -> ExecutionTracer

Returns the “default value” for a type.

impl<T> From<ExecutionTracer> for Tracer<T>

fn from(original: ExecutionTracer) -> Tracer<T>

Converts to this type from the input type.

impl PartialEq for ExecutionTracer

fn eq(&self, other: &ExecutionTracer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Tracing for ExecutionTracer

fn is_execution_tracer(&self) -> bool

Check if the tracer is an execution tracer.

fn dispatch_result(&mut self, base_call_weight: Weight, weight_consumed: Weight)

Called once the transaction completes to report the gas consumed by the meter.

fn enter_opcode( &mut self, pc: u64, opcode: u8, trace_info: &dyn EVMFrameTraceInfo, )

Called before an EVM opcode is executed.

fn enter_ecall( &mut self, ecall: &'static str, args: &[u64], trace_info: &dyn FrameTraceInfo, )

Called before a PVM syscall is executed.

fn exit_step(&mut self, trace_info: &dyn FrameTraceInfo, returned: Option<u64>)

Called after an EVM opcode or PVM syscall is executed to record the gas cost.

fn enter_child_span( &mut self, _from: H160, _to: H160, _delegate_call: Option<H160>, _is_read_only: bool, _value: U256, _input: &[u8], _gas_limit: u64, )

Called before a contract call is executed.

fn exit_child_span( &mut self, output: &ExecReturnValue, gas_used: u64, weight_consumed: Weight, )

Called after a contract call is executed

fn exit_child_span_with_error( &mut self, error: DispatchError, gas_used: u64, weight_consumed: Weight, )

Called when a contract call terminates with an error

fn storage_write( &mut self, key: &Key, _old_value: Option<Vec<u8>>, new_value: Option<&[u8]>, )

Called when storage write is called

fn storage_read(&mut self, key: &Key, value: Option<&[u8]>)

Called when storage read is called

fn watch_address(&mut self, _addr: &H160)

Register an address that should be traced.

fn terminate( &mut self, _contract_address: H160, _beneficiary_address: H160, _gas_left: u64, _value: U256, )

Called when a contract calls terminates (selfdestructs)

fn instantiate_code(&mut self, _code: &Code, _salt: Option<&[u8; 32]>)

Record the next code and salt to be instantiated.

fn balance_read(&mut self, _addr: &H160, _value: U256)

Called when a balance is read

fn log_event(&mut self, _event: H160, _topics: &[H256], _data: &[u8])

Record a log event
