Expand description

An inspector that collects call traces.

This [Inspector] can be hooked into revm’s EVM which then calls the inspector functions, such as [Inspector::call] or [Inspector::call_end].

The BrontesTracingInspector keeps track of everything by:

  1. start tracking steps/calls on [Inspector::step] and [Inspector::call]
  2. complete steps/calls on [Inspector::step_end] and [Inspector::call_end]

Fields§

§config: TracingInspectorConfig

Configures what and how the inspector records traces.

§traces: CallTraceArena

Records all call traces

§trace_stack: Vec<usize>

Tracks active calls

§step_stack: Vec<StackStep>

Tracks active steps

§last_call_return_data: Option<Bytes>

Tracks the return value of the last call

§gas_inspector: GasInspector

The gas inspector used to track remaining gas.

§spec_id: Option<SpecId>

The spec id of the EVM.

This is filled during execution.

Implementations§

source§

impl BrontesTracingInspector

source

pub fn new(config: TracingInspectorConfig) -> Self

Returns a new instance for the given config

source

pub const fn config(&self) -> &TracingInspectorConfig

Returns the config of the inspector.

source

pub const fn get_traces(&self) -> &CallTraceArena

Gets a reference to the recorded call traces.

source

pub fn get_traces_mut(&mut self) -> &mut CallTraceArena

Gets a mutable reference to the recorded call traces.

source

pub fn set_transaction_gas_used(&mut self, gas_used: u64)

Manually the gas used of the root trace.

This is useful if the root trace’s gasUsed should mirror the actual gas used by the transaction.

This allows setting it manually by consuming the execution result’s gas for example.

source

pub fn with_transaction_gas_used(self, gas_used: u64) -> Self

source§

impl BrontesTracingInspector

source

pub fn into_trace_results( self, info: TransactionInfo, res: &ExecutionResult, ) -> TxTrace

source

pub fn build_trace( &self, tx_hash: B256, block_number: u64, ) -> Option<Vec<TransactionTraceWithLogs>>

Returns the tracing types that are configured in the set.

Warning: if [TraceType::StateDiff] is provided this does not fill the state diff, since this requires access to the account diffs.

source

pub fn build_tx_trace( &self, node: &CallTraceNode, trace_address: Vec<usize>, ) -> TransactionTrace
