Defines methods to trace contract interactions.

Provided Methods

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

Register an address that should be traced.

fn enter_child_span( &mut self, _from: H160, _to: H160, _is_delegate_call: bool, _is_read_only: bool, _value: U256, _input: &[u8], _gas: Weight, )

Called before a contract call is executed

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 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

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

Record a log event

fn exit_child_span(&mut self, _output: &ExecReturnValue, _gas_left: Weight)

Called after a contract call is executed

fn exit_child_span_with_error( &mut self, _error: DispatchError, _gas_left: Weight, )

Called when a contract call terminates with an error
