Struct solana_rbpf::vm::Tracer

pub struct Tracer {
    pub log: Vec<[u64; 12]>,
}

Used for instruction tracing

Fields

log: Vec<[u64; 12]>

Contains the state at every instruction in order of execution

Implementations

impl Tracer

pub fn trace(&mut self, state: [u64; 12])

Logs the state of a single instruction

pub fn write<W: Write, E: UserDefinedError, I: InstructionMeter>(
    &self,
    output: &mut W,
    analysis: &Analysis<'_, E, I>
) -> Result<(), Error>

Use this method to print the log of this tracer

pub fn compare(interpreter: &Self, jit: &Self) -> bool

Compares an interpreter trace and a JIT trace.

The log of the JIT can be longer because it only validates the instruction meter at branches.

Trait Implementations

impl Clone for Tracer

fn clone(&self) -> Tracer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Tracer

fn default() -> Tracer

Returns the “default value” for a type.
