Struct CallTracer

pub struct CallTracer { /* private fields */ }

A Tracer that reports logs and nested call traces transactions.

Implementations

impl CallTracer

pub fn new(config: CallTracerConfig) -> Self

Create a new CallTracer instance.

pub fn collect_trace(self) -> Option<CallTrace>

Collect the traces and return them.

Trait Implementations

impl Clone for CallTracer

fn clone(&self) -> CallTracer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CallTracer

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

Formats the value using the given formatter.

impl Default for CallTracer

fn default() -> CallTracer

Returns the “default value” for a type.

impl<T> From<CallTracer> for Tracer<T>

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

Converts to this type from the input type.

impl PartialEq for CallTracer

fn eq(&self, other: &CallTracer) -> 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 CallTracer

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

Record the next code and salt to be instantiated.

fn terminate( &mut self, contract_address: H160, beneficiary_address: H160, gas_left: U256, value: U256, )

Called when a contract calls terminates (selfdestructs)

fn enter_child_span( &mut self, from: H160, to: H160, delegate_call: Option<H160>, is_read_only: bool, value: U256, input: &[u8], gas_limit: U256, )

Called before a contract call is executed

fn log_event(&mut self, address: H160, topics: &[H256], data: &[u8])

Record a log event

fn exit_child_span(&mut self, output: &ExecReturnValue, gas_used: U256)

Called after a contract call is executed

fn exit_child_span_with_error(&mut self, error: DispatchError, gas_used: U256)

Called when a contract call terminates with an error

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

Register an address that should be traced.

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

Called when a balance is read

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

Called when storage read is called

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

Called when storage write is called
