Variants

FourByteTracer

The 4byteTracer collects the function selectors of every function executed in the lifetime of a transaction, along with the size of the supplied call data. The result is a FourByteFrame where the keys are SELECTOR-CALLDATASIZE and the values are number of occurrences of this key.

CallTracer

The callTracer tracks all the call frames executed during a transaction, including depth 0. The result will be a nested list of call frames, resembling how EVM works. They form a tree with the top-level call at root and sub-calls as children of the higher levels.

FlatCallTracer

Tracks all call frames of a transaction and returns them in a flat format, i.e. as opposed to the nested format of callTracer.

PreStateTracer

The prestate tracer operates in two distinct modes: prestate and diff.

• In prestate mode, it retrieves the accounts required for executing a specified transaction.
• In diff mode, it identifies the changes between the transaction’s initial and final states, detailing the modifications caused by the transaction.

By default, the prestateTracer is set to prestate mode. It reexecutes the given transaction and tracks every part of state that is accessed.

This functionality is akin to a stateless witness, with the key distinction that this tracer does not provide any cryptographic proofs; it only returns the trie leaves. The output is an object where the keys correspond to account addresses.

NoopTracer

This tracer is noop. It returns an empty object and is only meant for testing the setup.

MuxTracer

The mux tracer is a tracer that can run multiple tracers at once.

Trait Implementations

impl Clone for GethDebugBuiltInTracerType

fn clone(&self) -> GethDebugBuiltInTracerType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GethDebugBuiltInTracerType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GethDebugBuiltInTracerType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<GethDebugBuiltInTracerType> for GethDebugTracerType

fn from(value: GethDebugBuiltInTracerType) -> Self

Converts to this type from the input type.

impl Hash for GethDebugBuiltInTracerType

fn hash<__H: Hasher>(&self, state: &mut __H)
