Struct Machine 

pub struct Machine { /* private fields */ }

A synchronous interpreter for one function of a validated Program.

Implementations

impl Machine

pub fn poll_async(&mut self) -> usize

impl Machine

pub fn run_instrumented<P: VmProbe>(&mut self, probe: &mut P) -> VmOutcome

Runs through the same production dispatch implementation while emitting compact scalar events. This path deliberately does not execute tracing JIT recordings; JIT internals have a separate telemetry contract.

pub fn resume_instrumented<P: VmProbe>( &mut self, state: PromiseState, probe: &mut P, ) -> VmOutcome

Applies one settlement to a machine stopped at Await, emits the resume or unwind boundary, and continues through run_instrumented.

impl Machine

pub fn step_instrumented_boundary<P: VmProbe>( &mut self, probe: &mut P, ) -> VmBoundary

Executes exactly one production dispatch boundary without projecting VM state. The caller may lazily inspect the machine after event/filter matching through the shared instrumentation hub.

pub fn resume_instrumented_boundary<P: VmProbe>( &mut self, state: PromiseState, probe: &mut P, ) -> VmBoundary

Applies exactly one settlement at the actual retained Await boundary. Subsequent instructions are left for later step_instrumented_boundary calls.

impl Machine

pub fn entry(program: Rc<Program>) -> Machine

The machine for the program’s entry function.

pub fn call( program: Rc<Program>, prototype: u16, args: Vec<Value>, captures: Vec<Value>, ) -> Machine

The machine for a function call: args fill the parameter slots, captures the capture slots directly above them.

pub fn run(&mut self) -> VmOutcome

Runs the function to completion or failure.

impl Machine

pub fn resume(&mut self, state: PromiseState) -> VmOutcome

Continues a machine stopped at Await. The settlement is applied at the suspended instruction so ordinary exception handlers see a rejected promise exactly like a guest throw.

pub fn resume_yield(&mut self, value: Value) -> VmOutcome
