Expand description

Nonoperative VM tracer. Does not trace anything.

Trait Implementations

source

impl VMTracer for NoopVMTracer

type Output = VMTrace

Data returned when draining the VMTracer.

source

fn drain(self) -> Option<VMTrace>

Consumes self and returns the VM trace.

source

fn trace_next_instruction(
    &mut self,
    _pc: usize,
    _instruction: u8,
    _current_gas: U256
) -> bool

Trace the progression of interpreter to next instruction. If tracer returns false it won’t be called again. @returns true if trace_prepare_execute and trace_executed should be called. Read more

source

fn trace_prepare_execute(
 &mut self,
 _pc: usize,
 _instruction: u8,
 _gas_cost: U256,
 _mem_written: Option<(usize, usize )>,
 _store_written: Option<(U256, U256 )>
)

Trace the preparation to execute a single valid instruction.

source

fn trace_failed(&mut self)

Trace the execution failure of a single instruction.

source

fn trace_executed(&mut self, _gas_used: U256, _stack_push: &[U256 ], _mem: &[u8 ])

Trace the finalised execution of a single valid instruction.

source

fn prepare_subtrace(&mut self, _code: &[u8 ])

Spawn subtracer which will be used to trace deeper levels of execution.

source

fn done_subtrace(&mut self)

Finalize subtracer.
