Struct Machine 

pub struct Machine<'a, H: Host> { /* private fields */ }

The production bytecode interpreter.

Implementations

impl<'a, H: Host> Machine<'a, H>

pub fn ordinary_number_to_string(number: f64) -> String

pub fn same_value_zero(&self, left: Value, right: Value) -> bool

impl<'a, H: Host> Machine<'a, H>

pub fn new( program: &'a Program<Verified>, host: &'a mut H, limits: Limits, ) -> Self

pub fn run(self) -> Result<Execution, RuntimeError>

pub fn evaluate(&mut self) -> Result<Execution, RuntimeError>

Evaluates the program without draining queued microtasks.

The machine remains available for an explicit Self::drain_microtasks checkpoint.

pub fn run_one_expired_timer(&mut self) -> Result<TimerRun, RuntimeError>

Runs at most one expired live timer callback.

This explicit checkpoint never drains microtasks. Expiry reports only advance a monotonic watermark; visible delivery is ordered by the machine-owned (deadline, sequence) key.

pub fn wait_for_timer_expiry(&mut self) -> Result<bool, RuntimeError>

Blocks in the host provider until an expiry report is available. Returns whether at least one live timer became ready.

pub fn has_pending_timers(&self) -> bool

Returns whether any machine-owned live timer remains.

pub fn run_to_quiescence(&mut self) -> Result<(), RuntimeError>

Runs queued microtasks and expired timers until both are idle.

pub fn drain_microtasks(&mut self) -> Result<MicrotaskDrain, RuntimeError>

Runs queued microtasks in FIFO order until the queue is empty.

Jobs queued by another job run in the same checkpoint. Promise callback throws settle their derived promises. Throws from queueMicrotask callbacks are returned in MicrotaskDrain::uncaught.
