Struct solana_rbpf::vm::TestContextObject

pub struct TestContextObject {
    pub trace_log: Vec<TraceLogEntry>,
    pub remaining: u64,
}

Simple instruction meter for testing

Fields

trace_log: Vec<TraceLogEntry>

Contains the register state at every instruction in order of execution

remaining: u64

Maximal amount of instructions which still can be executed

Implementations

impl TestContextObject

pub fn new(remaining: u64) -> Self

Initialize with instruction meter

pub fn compare_trace_log(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 TestContextObject

fn clone(&self) -> TestContextObject

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ContextObject for TestContextObject

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

Called for every instruction executed when tracing is enabled

fn consume(&mut self, amount: u64)

Consume instructions from meter

fn get_remaining(&self) -> u64

Get the number of remaining instructions allowed

impl Debug for TestContextObject

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

Formats the value using the given formatter.

impl Default for TestContextObject

fn default() -> TestContextObject

Returns the “default value” for a type.
