Struct StopView 

pub struct StopView { /* private fields */ }

SRD-92 Step 0 — one cooperative-stop view, consulted at every boundary. Bundles the per-execution stop sources so a boundary check is a single call, and so a unit that previously held only ONE flag (the while: wrapper held only the activity stop_flag) observes ALL of them. The global / per-execution session stop (stop_requested) is always folded in; a fail-effect global (fault_stop_requested) is folded into StopView::poll.

The daemon source (the SRD-82 Part 6 daemon-group completion) is a CLEAN termination: it ends a loop (StopView::stopped) but is NOT a fault, so it is excluded from StopView::abnormal (the failure-determining set). Fiber-pool scale-down ([crate::fiber_pool::StopFlag]) is a per-fiber concern, deliberately NOT part of this view.

Implementations

impl StopView

pub fn new( activity: Option<Arc<AtomicBool>>, walk: Option<Arc<AtomicBool>>, daemon: Option<Arc<AtomicBool>>, ) -> Self

Build from the per-execution stop sources (any may be absent).

pub fn stopped(&self) -> bool

Any cooperative stop — incl. the clean daemon-group completion and the global / per-execution session stop. Use at loop BREAK boundaries.

pub fn abnormal(&self) -> bool

A stop that marks the unit FAILED / abnormal — EXCLUDES the clean daemon-group stop. Use for the failure-determining return.

pub fn poll(&self) -> Option<StopCause>

The stop CAUSE for shell-level recording (SRD-82 Part 4): a fault (the activity error-handler stop_flag, or a fail-effect global) outranks a clean interrupt.
