GuardState

private class GuardState

One lane-thread's watchdog state — everything except that lane's ABI kill-id field.

Properties

caught

@Volatile

var caught: TimeoutGuard.Caught?

deadGen

@Volatile

var deadGen: Int

The generation whose budget the watchdog spent, or -1 (never a live generation). Compared for EQUALITY against gen, so a write from a body armed for an older frame carries that older number and reads as "not tripped" all by itself — which is what makes a watchdog racing a concurrent disarm a non-event.

depth

var depth: Int

Frame nesting, so endFrame can tell an inner frame from the outermost one.

gen

@Volatile

var gen: Int

Frame generation, bumped on every arm and disarm. Lane thread is the sole writer, so ++ needs no atomic. Only ever compared for equality, so wrap is a non-event.

stepEval

@Volatile

var stepEval: Int

Which eval is on this lane's stack right now, or 0. Changed only under this state's monitor, which is what pairs a step boundary with arm's kill write; volatile for the one read taken outside it.

timer

var timer: ScheduledFuture<*>?

Lane thread only, like depth — never read off-lane, so plain fields.
